Horror with a decapitated blue head in a chair?

Question

when I was young flipping through the channels on TV, I watched a single scene that scarred me for almost 5 years. It could be rated R because I was spoiled enough to have satellite as a kid. All I remember...

A small group of people climb into a library (maybe a school library )( which I assume was a basement because the windows were small and only at the top ). When they got in, they thought they were safe until somebody turned a swivel chair around and there was suddenly a man's decapitated head that was all blue.

If I remember correctly from the image quality it was a late 80s or early 90s film. People have told me "IT" but I have never seen it and that doesn't make much sense to me.

please help me relive my nightmares! Thanks!

Edit: could be a TV series, but it seemed pretty gruesome for tv. It was around 20 years ago, +/- 5 years in the US. There were 3-5 people that were between teens to 30s. The head itself was absolutely all blue not from the lighting. That image was seared into my brain.

Still haven't found anything and Halloween has made me revisit the idea. Any help would be appreciated and I will definitely share the answer if i find it.

Answer 1

It sounds like the movie was "House" from 1986 -scared me to death too. I was only a grade school kid and caught parts of it on TV, and the only reason I even remembered it was the commercials that came on said-we return you to House-and there is a blue head in the chair.
