Experienced my first weed edible high and it was scary crazy. I felt as if at first I was floating into space and couldn't stop myself I thought I was going to die, but I didn't so then after when I would rub my hands around I believed I could feel the little atoms that make everything, and later the scariest part in my opinion is that I had a song playing and the same section of the song kept replaying in my mind (it felt like an endless loop that I wouldn't get out of). All this didn't happen really though (I didn't float, nobody can feel each individual atom I think, and I definitley wasn't reliving anything)
What causes this? Like what does it do to a persons brain to make them think something is replaying? And does it impact your nerves to make you feel things much more sensitive? Anybody know?
