Here's some more descriptions I need some help finding the names to!

There was one movie where these people got locked into a basement in a house, and once in there was assaulted by some fat deformed man who came out of a heap of trash in the basement. This could have just been a dream I had, but regardless, I want to make sure.

Another revolved around a young guy and his friends going on a trip to an old house. Turns out the guy had accidently killed his mom while cleaning his father's rifle years prior. I think the guy ends up trying to kill his friends, or his father lurks about trying to.

Another movie involves a kid who discovers a monster in his closet and tries to convince his parents, but the parents do not listen. The monster eventually ends up killing the parents.

The 2nd movie that you talked about is the mulilator, at least i think it is. the movie is a big pile of crap, in my opinion, so you should probably not bother checking it out again. but thats me.

[Hans, wihout Franz]

The 3rd is called Monster in the closet. Its average.

Do you remember anything else about the first movie? For some reason the movie Humongous pops into my head.

Nope, that's all. I think the people who were trapped in the basement were actually invited there by the residents but were betrayed and locked in the basement with this fiend.
