Dream interpretation, very strange

Hello. ID like any insight on this dream.

my dad and I are sitting at a picnic table in a gazebo. It's supposed to be in a park, but there's very little grass. Loose brown dirt, mostly. We can see the parking lot.

We are eating sandwiches, when an attractive woman comes and sits at our table. She asks us if we know how to break into a car, and motions to a green Taurus. She says it would be very helpful, and proceeds to spread her legs, flashing my old man.

Well, he's convinced. They set off, and I'm left completely fucking baffled. I look down at the table to grab my sandwich, as I'm too stunned to do anything else. When I look up, there's 4 well built Latino gentlemen stomping my dad into the dirt in the parking lot.

I react quickly, somehow managing to dispatch the four men. There was physical confrontation, but it was too fast and blurry to remember what happened. All I know is that my dad got his ass busted, there's four guys laying in the dirt, and I'm standing there without a scratch on me.

I proceed to drag dads ass back into my hotel room. Dunno why I have a hotel room, but I do. My wife is there. I lay dad down beside the bed. Not on it, on the floor beside it. I tell the wife to call an ambulance. She asks what happened, I look at her and say "Dammit, just CALL!" I look over to where I laid dad, and he's disappeared.

I wake up very suddenly. The hotel and park are gone. I'm sitting in water, inside what seems to be a cave. There's light, but it's dull yellow light. Wrong light. It makes my skin crawl. I start walking, trying to find a way out. I come upon a large alcove. The girl from the park is here. There's another woman too, pale, deathly pale, black hair.

And she's naked.

The pale woman commands me to have sex with the redheaded girl from the park. Unable to resist, I do. I start hittin it from behind. The pale woman sits beside us, and begins to masturbate. This should be insanely hot, but it's wrong, something is wrong.

The pale woman clicks a remote. A movie begins playing in front of us, on a wall that is miles high. The wall is all pipes and jagged metal. It's a movie of the pale woman and the redhead.

The redhead tells me to stop, it's hurting her. The pale woman says, "Ignore her. Keep going." I look at the movie. The redhead is tied up, and the pale woman is torturing her. Whipping her unmercifully, then beginning to cut her with a razor. I try to look away, but I can't, whatever it is won't let me. As the pale woman begins to cut the redheads throat on the movie, I'm finally able to break my gaze away, I look at the pale woman beside us. Her crotch is cracking, tiny lines forming in her pubic hair. Filthy dull white light seeps through the cracks.

All the sudden I'm alone. Same cave, same piped, metal wall. Before me is a metal construct jutting from the wall. A human brain is attached at the end, and somehow I know it's alive and aware of me.

The end. Somebody tell me what it means.
