Are you inspired?

It seems to me that inspiration comes at the strangest times. I can struggle for ages to find an idea of what to write for an english internal or (more importantly) my blog. Then suddenly when I am furthest from my computer or just about to go to sleep an idea will hit. Of course my brutally scientific mind says that there has to be an explanation for this. Maybe as I am about to sleep I have less time to pick an idea to pieces and the ideas just seem better. Of course I can never test this by looking at these ideas while awake because I have this annoying habit of forgetting them. As Douglas Adams so beautifuly puts it
"And then, one Thursday, nearly two thousand years after one man had been nailed to a tree for saying how great it would be to be nice to people for a change, one girl sitting on her own in a small cafe in Rickmansworth suddenly realized what it was that had been going wrong all this time, and she finally knew how the world could be made a good and happy place. This time it was right, it would work, and no one would have to get nailed to anything.
Sadly, however, before she could get to a phone to tell anyone about it, a terribly stupid catastrophe occurred, and the idea was lost forever."
Of course I'm not debating any problems of world wide concern, as far as I know, but I still get that feeling that at some stage I had the answer. I had the solution to all (or atleast some) of my problems. And poof. Gone. Forever, well, maybe forever is an exageration maybe "for a very, very long and painful time that 'tends to infinity' " would be more accurate. But these ideas, strange though it may be, give me a glimmer of hope. Surely anything I had and lost I could get back again.
I hate the fact that even I do not understand what I am saying (or maybe what I mean by it) I get so lost in metaphors and euphimisms that I can't figure out what I mean.
