In the spring of 2016, I attended a month-long jhana retreat and build up Samatha according to TMI. When I reached the 7th stage10 of Samatha, a memory of an upsetting event (that I identified at the time as a repressed memory) burst into consciousness. The upset was so great that I lost two complete nights of sleep and was unable to meditate during the day. Realizing that I could not just meditate my way through this crisis, and that the lack of sleep was endangering my health, I left the retreat and drove the 5 hrs home in the middle of the night. Once there I was able to determine that the so-called repressed memory was in fact a false memory, something that my unconscious mind had fabricated out of some scraps of real memory plus gross distortions based on insecurities. I caught up on some sleep and then drove back to the retreat centre to finish the retreat.
The insecurities brought up to the surface during the retreat took over a year to get resolved. I went to see a few psychologists and other therapists but did not get much help from them. It is only when I fully admitted to myself the presence of these insecurities since childhood, that they were fully exposed and recognized, that they got integrated and stopped having an impact on my life. That was a valuable experience from the point of view that I can now empathize better with those who suffer psychological problems.
