You might be an alien experiment if you claim you had experiences with the grays .For all we know , you could be a father. I mean no joke , just implying that most of the children who had dreams and later grew up , with the mind control thing where the psychologist puts you in a trance to see the memory that has been blocked by them , they realized they had "space" children at some one point in their life.
When you grow up , remember to go to such a thing and see if you had a third degree encounter and memory wipe.
