Is this normal?

I am constantly having old dreams come back to me, almost every day I have been remembering dreams that I had a long time ago. Not that I forgot them before, they just keep popping up out of nowhere.

When I was younger and experimenting with drugs, I ate poisonous mushrooms for the psychedelic experience. The worst part of the experience was when I could not put my mind to rest and I couldn't concentrate on what was going on around me because my dreams kept coming into my memory as though all those dreams really happened, as though my dreams were my alternate life. Very hard to explain. I kept thinking of what my world looks like in my dreams, and things that happened in my dreams, and places I had been in my dreams, things like that, but it was years of dreaming coming to me all at once. I couldn't control it and didn't stop crying until it stopped.

Is this pretty normal excluding the mushroom effects?
