I didn't see this movie in the 90s myself, but I did see it later on in the late 2000s. It's a psychological horror film about a vietnam war veteran who starts to hallucinate messed up things and deformed monsters. It holds up really well today and I would highly recommend it for it's creepy atmosphere. Here's a trailer to get an idea.
It's become one of my favorite horror films.
