Dreams

Does anyone know how to stop yourself from dreaming?
No, not day-dreaming.... The sleep dreams.
Can you stop them? I'll probably go mad if i can't.

Today i dreamt that my grandma died.
Before that i dreamt of something just as freaky.
The day before i had a dream inside a dream inside a dream. And i was asleep for just 1 1/2 hrs. And the dream wasn't pleasant.
Sometime before that, i dreamt of being convicted for a crime i hadn't done and someone dying. I woke up crying.


Someone make it stop. Please.

P.S. I've decided to keep a dream diary from now on and record my dreams before i forget them and also how frequently i dream.
If i sleep less than i do now, will it stop? I sleep 5 hrs nowadays.
