i had a dream about Kurt cabain what happened was i came home from school one day and went up stairs to my room and then i saw him sitting on my bed crying saying i did not do it. then i woke up frighten kind of strange dream is it ?

I once had a dream that this mass murderer hated this family, so he kidnapped the youngest son, cut hime in half, put him in a purple trsnsparent bag, pushed him down a laundry shoot that for some resean lead to a telephone pole outside, where the kid sat in half for a whole day just hanging there. When the family found him, the family doctor sewed him back together.
And that is just one of the hundreds of wacko dreams I have had.

dreams i think are an expansion of our sixth sense

Try having a dream where you are fighting in World War Two, or Vietnam is the one I had most recently.

Or being trained to fight in the military.

Or bringing someone back to life as you are playing the part of a doctor working in the ER.

Like Ikki said your dream is not all that scary.
You could Google "the meaning of dreams" to find a resource on what your dreams are really telling you. Some of the stuff on those sites are kinda hard to take seriously though.

Have you ever dreamt that a dinosaur fossil structure was in your living room with a play set and that some old women died and the world went to hell?

How about someone fell off a roof and suddenly, there was fires everywhere?

How about an enemy bombing you with huge paintballs and there was an underground room full of books that you needed to save, all the while while trying to save Bigfoot?

Your dream really isn't that strange.
