once, I was sleeping on the edge of my bed with my parents, and a monster that looked quite similar to the gohst busters gargoil, but much smaller just sort of came up right in front of me. doesn't sound to bad, but think about it, you are a little kid and this thing just shows up, eyes glowing less than half a foot away from your head, totaly lit properly looking totaly real. I froze for a second it just sort of stayed there stairing at me untill I freaked out and turned twards my mom, when I turned back it was gone.
there was another common monster it was basicly just a set of huge hands that if I ever put my feet on the ground he'd grab me, and presumably do something unpleasent that I didn't want to find out. now that I think about it, the hands were about the size of a Vasudan hand... though they were a bit meatier.
now the realy scary one was this one time were I had this hypothosis, if I was under the bed when the lights whent out, the monsters couldn't be there, and then all I'd have to do was keep the ones in the closet at bay, and the dog was good at that, so, I go under the bed and try sleeping there, it works, first night, no monsters not nothing. next night, same deal, I'm prety hot **** no? keep doing this untill eventualy, one night I'm under there and thinking about it, trying to get to sleep, then I see something at my feet, something glowing, sort of a green glow like glow in the dark toy type things, two circular shapes, two eyes just a bit above my feet, looking right at me. I think: "hmmm, well I guess I wasn't right after all was I. nope not right at all, there is a monster, right next to my foot... crap!" I don't move for a few seconds, looking at it looking at me, and I think: "well it doesn't seem to be atacking me, maybe it's not a monster, it sort of looks like a couple glow in the dark constructs (a toy I had in great abundence) maybe there were a few of them under here and I just didn't noice them untill now, and for some reason they are hovering half a foot in the air" so I bend over to touch them (obviusly a briliant move, lets put our hand on the mouth end of a monster) and just as I'm thinking well it hasn't moved sence I started bending over it's probly nothing, they rushed right at my face, my hand whent right through the middle of them and they went right through my head and out from under the bed into my room and disapeared. I then proceeded to freak out and scream and run to mom's room running into my door then opening it, then running into her door then opening it, and continued to freak out for some time.
the oldest monster I had to worry about as a kid, was this nebulus floating thing that only came out in the dark, funny thing about this is I can still see it, it's a real optical illusion, go into a dark room and look into the darkest corner you can find, there'll be a little tingle of light caused by the receptors in your eye fireing randomly every now and then
and there were a bunch of snake things, holes would form out in the yard and a hord of large snake monsters would come out, I'd have to seal up the room I was in to keep them out, putting towens under doors and locking windows, putting heavy objects over top air vent's ect...
all of these manifested themselves in full blowen halucinations at least once, includeing both sight and sound.
