Is astral projection genetic?

[BOATS]

My grandmother had the ability to naturally OBE and never has read a single word on it.  Also my sister gets sleep paralysis.  Her daughter also gets sleep paralysis.  My mother has seen apperitions of her grandmother.  My ex wife who I consider a soul mate also gets sleep paralysis.  To my knowledge no one has been aware of sleep paralysis or OBE in my family beforehand.

Looking back on my past experiences, I've come to realize that many of the "dreams" I've had during the course of my life were infact projections. I'm starting to believe that I've been projecting for much longer than I realize. Something Interesting to note is that my uncle (on my mom's side) has apparently bilocated a few times. My mom, her sister or their mother would see a ghost of him walking around outside the home when infact he was at a friends house or some other location far away from the house. My mom saw him maybe 4 times. I'm not sure about the rest of her family. but the ones who have seen the "ghost" of him have sworn up and down that it was indeed a ghost and that he wasn't home when it took place.
My uncle died in a car wreck a few months before I was born..so I never met him. After he died, they stoped seeing his ghost wonder aroud from time to time. It was a very strange occurance to say the least. I was wondering if there is a genetic element to projection that makes some people more inclined towards it. Perhaps my uncle could bilocate because he projected on a regular basis and there was apart of him that was simply more apt at the whole thing. I never got a chance to talk to him and ask. All I know is that he did infact bilocate and I project. I know a lot of people project..but I sometimes get the feeling that there might be something genetic in the way of paranormal occurances. what do you think?
