Hello. First post here. Glad to see a community so pratice oriented.

I have So been meditating for 3 years and did 3 goenka retreats. The last one, in which the following events happenend, was really profound.

Several days in the retreat I observed that most body was energy and there was no solidity except in very specific places (chest mostly).
When i went to sleep on the 8th day, I had a "dream" that was so vivid it was a literal as "real" life.
 While labes don't aways help, for explanation reasons i'm gonna name it past life because of the deep ressonance it made.
So basically it's me arriving home, which i fled, after a long time away, and greeting my mother (different from my "real" mother),
and she's really emotional for seeing me. It happens that for some reason - a traumatic event (which is probably extremly obvious)
 I supressed all my memories as way to deal with the pain, which turned me into someone with something closed to dementia. It happens that when i got back home with my family i made a resolution to deal with trauma altough i was
very handicaped at the time (couldn't find the places around the house, was very confused etc). I had a brother my age who was very happy to see me and helped and supported me alongside my mother.

Long story short i start to lose courage again, and start to lose memories and functionality. At some point i forgot my brother's name which is one of the saddest moments i remember.
Everything looks foggy and confusing then.
I'm almost going hopeless but then for an instance i remember everything, even the trauma that is haunting me but this thought occurs - "While i fled from home my mother gave up up on me. And then this the moment of realization: It looks like this live im going through is a reflex of the flow of that life, that all that im going through is a paralel mirror.
That by changing the course of action (e.g dealing with the trauma) in that life "I" will cease to exist.
And it's really sad.

It's just like that movie "The Fountain", it looks like the actions carried pull you trough the time dimension and everything keeps happening in loop untill you realize truth.

I need to see truth, what diagnosis do you make based on these events and what advice do you give to go trough these episodes?

The body sensations experienced alongside these occurences were like it was "ready" to happen something like a kunndalini awakening, but because there was a lack of courage to look to the cause of suffering it is as it's not happening.

Further information:
I have reached 2nd jana some time ago, but recently more its been a challenge to build concentration because there is a lot of resltessness in the meditation. Overall in the last year i'm feeling a lack of energy and "purpose", more withdrawn socially, there is a bigger need to rest..
If you need further clarifications feel free to ask.

Thank you.
