anybody else enjoy "nightmares"?

I use the term loosley because i enjoy gorey violent dreams..
i have always had them so to me they are just dreams..
like one i had
I was in my old highschool,
It was dark grey outside and i was in the loading area(were we hung out smoked ect)
but it was silent..i looked around and heard a squek and slipped looked down and it was a dead guys brains...

I then proceeded to go to the cafateria everyone was having lunch despite a lot of dead bodies in a room not 100 feet away...
i head upstairs i see no one so i walk down the hall and proceed to the lunch room were no one is now????
confused i walked out through the loading bay looking at the bodies for some reason..
as i get to the door a man who idenifies himself as a police officer tells me there is a murderer loose...
And i proceed to climb into the officers model t (yes)
And we proceed to go after the killer...
that's as far as i remember...
but yeah i like this kind of dream i think because its a mystery??

strangely yes.. I rarely have them but when I do its such a rush capped up with waking up in terror.
There was a recurring one about a gigantic plane I used to have, and it used to make this terrifying noise. Not a scary dream per se but I always experienced feelings of terror when I had it.
