If you've never seen Poltergeist (early 80's Horror Movie), then you won't get the quote above.
However, with the new GoPro Hero3 having landed in store this morning, you'll be able to make your own movies and with the outstanding quality of these cameras, you should be able to out-Blair the Blair Witch Project if you're that way inclined. Alternatively, you could try falling from Space like Felix Baumgartner, who used the GoPro on his record breaking freefall descent, or you could just film your adventures on a bike, in a boat, on the rocks, wherever you go.
