Is THC a stimulant depressant or hallucinogen?

Technically, marijuana would be considered a hallucinogen, since you tend to hallucinate. But from my experience, I've found it to be a relaxant. After it slows up my heartrate like a stimulant would, it as well slows everything down to an lower rate, and it's clear that everything in my body stops working at normal pace. Also, it makes me very calm.
