Was I possessed? What explanation can you offer for this?

When I was a child I was convinced I had died in a car crash, at three years old I could tell my Mum every detail from the road it was on, the number plate/ colour of the car etc. I had no concept of the roads outside of my own at 3 years old, or car number plates. My Mum just told me I was imagining it and consequently I forgot about it, only to find out recently that I thought that, and Mum wouldn't give me any details. I also used to be surrounded by orbs I every picture up until I was about 11 (when film cameras where more popular), no matter what camera was used, or if there was a flash or not. Sometimes the orbs would for shapes, I can specifically remember a dog, because when I was younger I liked dogs so it was cool to me. The shapes where much clearer and representitive of the things they looked like than constellations for example but they shaped were made up or lots of little circles so as clear as a dogs head can be made out of circles. Sometimes they'd form rings and all sorts. I asked Mim recently if I can see the pictures, she says she doesn't know where they are or some other excuse. I feel like she's hiding stuff from me. When I was born I suffocated and had to be rescucitated, just invade that has anything to do with it.
My Mum's a phsycic who predicts death and illness, she's pretty exact. Most recently she predicted her mothers death, fun. Her Mother wasn't old old, she hadn't spoken to her in years so had no idea what her physical health was like, just to say. She always warns people when they're going to be ill. I don't know whether that could be something to do with why she's hiding it all from me.
What do you think could have been the reason for all the weird stuff when I was younger?
