Glad to have you here
I believe I've been dealing with a similar "feeling" on and off for the past few years. I could try to describe it in detail (and have, and probably a bit too often and long windedly sometimes) but to put it succinctly it's almost a feeling of "unreality" or as if thing's (my perception, reality and life itself) are about to "flip" over on themselves .. As if I am about to realize I am dreaming.
There are plenty of people to talk to here and I"m certain you'll have some interesting conversations ( even if you don't find "the answer" .... or the "SEKRET" (Shhhhh)
