Hiya, good to see you back - It was your initial question which actually inspired me to do
this experiment, so you may find something of interest on that thread too. I'll go through your post and respond to specific points:
Hi, I’d like to introduce myself and get some feedback from some of my fellow yogis. I’m using this moniker temporarily because I can’t afford to have admissions of drug use out on the internet. I’ll think about this some more later and decide what to do. Maybe I’ll make a different account with my real name or just let people know individual who I am that I’d like to be friends with
It's not a big deal if you'd rather use an alias, the name I use is just a contraction of my full name but it's obscured enough to make it unlikely that anyone who knows me offline would make the connection. I don't use my full name because too many employers use "social media checks" nowadays and I'd rather my explorations and adventures remained seperate from that part of my life. Moniker or not, you can always PM people/have them PM you if they really wanted to know, and keep your identity otherwise hidden.
This whole section sounds very familiar to me, I also came here having had a shitload of these deep insights into things before ever having heard of vipassana. In fact, I'd gotten Path before I even knew what the hell it was!

1st Goenka 10 day Retreat Nov. 2010
Almost certainly an A&P Event, strong insights which should hopefully now inform your overall view of this thing.
Dissolution.
Cycling from A&P through Dark Night into Equanimity. If you've been able to hit Equanimity consistently then you're likely to land Path with a bit of refinement in your technique...if you don't already have it, that is.
After-effects of strong concentration while on retreat → Back into cycling. How long was it taking in your sits, if you can recall, before the sexual feelings began to arise?
Frustrating, ain't it?

lately there is a flickering effect present in all senses. like in the movie theater when you can notice the film flickering on the screen, or like sound is all little wavelets, lmy body feels like a metal pole that has been struck on one side and it is ringing, vibrating back and forth, in and out.
Have you tried looking at what happens when one of those "flickering" effects actually stops? Where does it go to, and where does the next flickering effect come from? For example, if you imagine that these "wavelets" look like a sine wave: What's happening when the wave gets to the lowest point of the 'trough'?
my body feels like a metal pole that has been struck on one side and it is ringing, vibrating back and forth, in and out.
What's going on at the 'other side' of this "metal pole"? It's been struck on "one side", but what sensations are implying that this "pole" has two sides to it? What's implying "back and forth, in and out"? Back and forth, or in and out from where?
I should mention that the 2 hours a day is formal sitting, I find that most of the day I am meditating as I do my activities, which might explain why it seems I stay in equanimity, even high equanimity throughout the day, for long periods of time.
Have you tried bringing noting into your practice in daily life? It can be incredibly effective if done properly, but, by the sounds of it, you shouldn't have any problems.
I was noting specific sensations, like itch, pain, bird chirp, circles, etc, but recently I've reduced my noting to 5 different options (...) By the time I have an attention moment that combines two or more sense doors, I generally just drop noting and try to observe attention. If focus starts to wane I go back to anapana for a bit, then back to noting
Excellent, now turn the attention towards the sense of somebody/something which is still observing; where (and what) is the subject still perceiving these objects in the mind? How does that happen? Are those sensations any different or more special than any other?
Lately, very subtle sensations are revealing themselves, like “body map,” “eye map,” “ear map,” and then these maps or projections start to themselves break up into flow, and I am disembedded from the subtle memory of being in a location specific in time and space.
Doubly excellent, this is some strong practice, in my opinion, and some nice descriptions too. Again, look at what's still implying that there is an "I" or any sort of observer which seems to be experiencing this moment right here. All of these concepts you can note in the mind are just that: concepts, they are empty, luminous, self-liberating 'particles' of awareness itself; what is it that's still making a distinction between the sense experience and the conceptual representation of it? What still implies a "you" who's experiencing "this"?
So in my estimation it appears as though stream-entry is pretty close, although I’m not entirely confident that my experience lines up exactly with that of someone on first path as I have already “seen the no-self” Shinzen Young says. And I have seen it in the most profound way I can imagine is possible, albeit outside the vipassana tradition.
This is where the whole Path thing get more complicated, particularly if you're not familiar with this particular model of experience, i.e. the Theravadan model via Dan Ingram's MCTB model. As you've said yourself, the benefits are evident anyway and, to be honest, the Path system, while helpful and encouraging, can set up ideas about goals and attainments which you don't really need. It took me a long time to be able to drop the maps and understand this in my own terms, but it's useful to familiarize yourself with other conceptual models; it allows a flexibility of thinking which sticking to one model completely destroys, and is useful in practical terms too.
However, I am working on the assumption that this “blip” or “wink of nothingness” is actually something that I will notice, and have an impact on me and not just something that could pass by without having some sort of gravity to it. Because there are often times little blips all over the place if I look for them in between attention moments or at the end of an attention moment. I don’t consider them a big deal, and I don’t think they are the blip people are talking about as nibbana, unless all of you are all under some sort of group placebo effect by imagining this as a big deal.
There are "blip"-like things that can happen between 2nd and 4th vipassana jhanas, but Path itself is utterly unmistakeable; much as it's been said a million times before, "you'll know when it happens" really is the easiest and least outcome-seeking/goal-pursuing way to put it. As for whether or not Fruition, the non-event "blip" in 'reality',
is the direct experience of Nibbana, that's a complicated and technical, not to mention historical, area which I know very little about; experientially though, when it happens "your" life changes in the most inexplicable way which you literally can't imagine.It seems like nothing has changed, but somehow everything has changed and the clarity is wonderful.
Whether you've already gotten Path, I don't know, but you certainly sound as though you're on the verge of tipping it. Whether that's onto 1st or 2nd path seems unimportant to you anyway since the results speak for themselves. Your practice sounds strong and it'll be cool to see how you get on, best of luck and practice well!
