I absolutely do believe in spirits and ghosts, too. I've had first hand experience w/both. I'm not gullible but I believe in things that I haven't necessarily experienced first hand. There are too many reports of the unexplained. I can't see the wind but I can feel its effects, so seeing is not believing for me. I do concur w/the point made that sometimes the mind wants something so badly that it conjures up the experience, which may or may not be the case here. However, if Heath Ledger did not depart this earth in peace, he may still be hovering on this plane until he finds peace and/or is able to impart a message to his loved ones.
