I also saw this movie as a kid and was haunted by it for a long while. I still remember being scared of the little creatures. There was another somewhat similar TV movie called Trilogy of Terror (just found the titles of both of these movies on the web out of curiosity) with Karen Black where she was haunted by a little voodoo like creature with a spear that also really got me good. As far as the effect a scary movie had on me at the time I saw it, this was by far the scariest movie I have seen in my life. I don't know if it would have much an effect on me now or not but it certainly did then.

I'm guessing it is not available on DVD or video.
