Dreams and memories, i think sometimes people can't tell the difference.

Several of the MUFON cases I've had were based on hypnogogic or hypnopompic dreams/hallucinations or were they?
Some cases I've heard of may have been implanted by telepathy. In one case the person experiencing what he thouhhy was an abduction cut himself so as to create a scar so as to proove that it actually happened.
