my little sisster told me once when she was about five. that she remmbred these three people that would stand around her crib when she was an infant, and they would teach her things. i was blown away that she would remmber, and say that. have you ever seen babys that would just laugh at nothing. i think ive allso seen my spirit guids when i was about 5 i saw three dark hooded figures standing infront of a mirror. i wasnt scared, and even spoke to them. i donnt think they expected me to be in the bathroom so late at night. i must of caught them off guard. has anyone ever seen there spirit guids in waking life like that?
I heard that babies see SG , they’re more open to this and also they keep the secret…
Now when you say it i remember a thing. When i was about 6 a girl in my class said something like “I have a friend only I can see”. Maybe she was referring to her spirit guide 
When I was isx or seven I saw a man with a blakc clothers and a hat looking at me all the time , and whne I turned around he disappeard…
I used to hallucinate when I was younger but I suspect it was Hypnopompic imagery.
