The Things I See And Feel

Ever since 2006 I was in a bad car wreck where my mom flew 90 feet which she survived but when she flew I was stuck in the car trying to get to her kicking and screaming, saying that's my mom she needs me. Which they wouldn't let me out said I hit my head pretty hard that day I blacked out and can't remember what happen. Ever since that day I see people that others can't see everywhere I go. They stay outside my house. I don't know who they are. The other day I passed a car accident where this young women was dead head in the steering wheel and as I passed it she lifted her head to look at me. I woke up the next day and there she is staring at me from outside. I also had this weird exp when I tried to sleep something came inside me screaming showing teeth, I was screaming and clenching my wife's hands hard, when I awoke I asked her did you hear me scream she said no also she didn't feel me squeeze her hand. This is all new to me yes I've had it since 2006 but I don't understand and to be honest I'm scared. I'm not sure why I see them and I can't figure it out so please if you think you can help me I would be very happy to hear your comments, I'm not sure what they want why is there more and more coming is there a reason why I was picked so many question. Looking for answers or help how to go about this I just don't know if I should talk to them I'm scared every day when I look outside I see them or when I'm driving or at a different house they always fallow me. No matter where I am.
