One of my favorite cheesy horror movies:  
Beware! The Blob!  I remember when I was seven or eight years old, watching this on late-night TV with my sister and several friends at a sleep-over at our house.  It scared the crap out of me!  Now, it's just a gelatinous pile of cheese. 
 
 At that time, I used to sleep with my arm under my pillow and my hand sticking out from under the pillow up by my headboard.  After I saw the first part of that movie (I was too scared to watch all of it), I was afraid that The Blob was under my bed and wanted to eat my hand!  Not 
me, just my hand.  I couldn't sleep with my hand sticking out after that, and haven't since.  I have actually tried a couple of times when I was older (when I wasn't scared anymore), but it was just plain uncomfortable.
