Forget it -- I see now. When I watch my toaster toasting my toast, I don't need a scientist to tell me its working. But when I find myself suddenly thinking of someone I haven't talked to in ages, and a minute later the phone rings and it's them -- or when I have a strange and vivid dream only to watch it really happen later, just as I dreamed -- well geez I better not trust myself to know I've just watched 'precognition' at work. Oh no! What *was* I thinking! (thumps forehead) How could I possibly trust myself to know that anything I've experienced directly, first-hand, on a regular basis all my life does really 'work'?

Better call Dr Science!   :-)
