Don't know if anyone has ever had this happen to them but I caught myself mid dreaming. Its like having a life shattering a epiphany...I'm getting goosebumps thinking about it right now...
Basically, it started out like any dream, don't know when I actually fell asleep I just did. I went to see some movie theater and some random things occurred, saw some familiar faces and some not so much (but interacted with them like I knew them for years).
I then blanked out and started walking in some unknown community, to some apartment building and open the door (guess I lived there). I started walking up the steps and took a turn to the right around the banister and looked at the table to my left. Thats when I realized everything was wrong, this isn't my life and I remember saying exactly this to myself "this must be a dream?". I started to feel a rushing feeling in my body and then appeared in some bedroom (not my actual bedroom) for a few seconds. After that I snapped back to reality...
I'm still reeling over that sensation.
