It's Alive (197x date)- prolly saw it when I was 9 or 10 on TV. A couple days later I got home from school and discovered I didn't have the housekey. So, being resourceful, I decided to go thru the 'crawlspace' under our house thru a little open vent section (I was real small back then lol).Then it would be a quick crawl/crouch about 20 feet, push open a panel, and I was in.
Unfortunately, about halfway in (headfirst mind you) I heard these..........noises........and I SWEAR TO GOD it sounded just like that freakin' baby sounded in the movie!
There I was, halfway thru the vent, looking into pitch black, and I'm hearing these noises. Not.good.at.all. I think I was screaming something like 'Vampire Baby! Vampire Baby!' to my sisters outside lol.
I still dont know what it was to this day. Since the vent 'cover' was missing, maybe some cats or something took up residence under there (it was just a dirt floor anyhow). But yeah, that left a rather nasty impression that I can still look unfavorably upon to this day.
Oh, and 'Dont Be afraid of the Dark'. Those little alien bastards gave me the heebee jeebees for a while. My sisters watched it too, and later they would whisper my name from across the room to freak me out......gah!
