Waking from a dream with it fresh in your mind is indespensible for writing emotive/epic lyrics...even more so when you have a night terror and it 'sticks with you' throughout the day...

I woke up today after a night long struggle of a dream(I'm actually mentally exhausted).It had quite a bit to do with the novel IT by stephen king,but different in so many different way's...not to mention I was experiencing it first hand...the feelings that passed through me,the pain I felt as I watched myself being slowly crushed under a slow moving train...worse than any snuff film ive ever seen.The train pushed off..I screamed,losing breath as the train surreally rolled over my spine and ruptured my lifes sustanince.

The emotions conveyed within dreams can be so foriegn...things that can never be felt while awake.Its not to say these feeling and events do not occur in reality..but the intensity lends different perspective...even though you wake up intact.
