I'm afraid I starting drifting off whilst listening to this.
Erin, you are either:
1) Completely delusional, 2) An exceptionally gifted pathological liar, or 3) You're actually experiencing things most philosophers and scientists would dismiss as impossible.
I don't think you're 3) and you don't sound like 1). That only leaves 2). However, I don't believe you are 2) either.
I believe that you really believe what you're saying is the truth. I'm not implying it isn't, I'm just stating that I don't believe you're purposely deceiving people.
You mentioned an incident which involved you receiving a hard knock on the head when you were 4 years old. Just a thought, but perhaps that knock on the head you received didn't result in you having psychic powers? Perhaps it made you crazy!?
I'm sure you will assert that 3) is true, however I am unable to disregard my rational belief system because of someone's personal anecdotes. Sorry.
