What separates the normal from the paranormal?
This depends on the attitude of the person interpreting the experience. Those who believe psi is impossible will always look for normal explanations, no matter how implausible. Those who believe in psi will look for mystical explanations when normal ones typically suffice. Parapsychologists feel that normal explanations cannot adequately explain all the recorded experiences, and therefore feel that all the answers regarding this topic are not in yet.
