I often experience vibrations when sitting in a chair or laying in bed - particularly in the evenings after a long day. This has gone on for years.

They are generally felt in my lower spine and surrounding back muscles, my glutes and my upper hamstrings.

I can't really put a frequency on it, certainly more times per second than I can count. It's like there's a very content cat purring deeply somewhere between my lower back and my butt.

There is also some kind of resonance via a second much slower period overlaid on top of the period of the first vibration. Maybe every second or two it cycles and seems to be running farther (from around the back of my knees up towards the middle of my back and down again, occasionally reaching as far as head to toe).

Neither period seems connected to my breath.

Once, when laying in bed and listening to binaural beats, the frequency of the tone in the headphones matched the frequency of the vibrations and they travelled all the way up into my head. My internal visual field became mildly psychedelic. At some point later I woke up from a dream that I can only describe as experiencing an endless yellow / orange / red fractal hypershape.

Anyway: I'm curious what these vibrations are? Is there a skillful (or interesting) way to work with them? Or are they just something to observe and live with?

I saw a post here that mentioned a thread by Tom Otvos about energy blockages, but I can't seem to find that thread? If anyone knows where that thread lives I'd like to read it.

Browsing around a bit, this community seems fantastic. Thanks very much for having me here.
