I had a similar experience as your when I was living in Tonga.I smoked up some weed my freind grows in his yard and I walked home and tried sleeping and I could swear there were people in my yard talking,I kept looking out my window and saw no one I even went outside and walked around my house at 1am(I felt like such a chronic) but I remember seeing these white things that looked like spirits flying around,it was weird.
