Nukie (1987). Yeah sure there's worse titles than this, but I guess you could say that this one's personal. Way back when I was probably 10-12 years old, I don't remember exactly.. anyway, that's not important. The day I was at the VHS rental store, I chose this. Overnight, I went into some kind of flu with a high fever. So I put this on to watch, thinking it would help keep my mind off being sick. As I lay in bed, too sick to move, I witnessed and endured this space turd creature walking around in a jungle and/or desert, constantly saying his own name like DJ Khaled.
As I went in and out of coherency, I kept hearing the strange voice saying "New-key. Neeeeew-Keeeeeey!". I hallucinated several times that Nukie was reaching his arms out to grab me, closer to me each time. Thankfully, I eventually went fully asleep and when I woke, my fever was gone and only peaceful bliss of TV static was on the screen - Nukie was over. As a child, this was horrifying. I've never forgotten it, no matter how much I've tried. As an adult, I can laugh a bit about it now, but wow what an experience and never again!
