It probably won't help that much, unless if you achieve REM sleep prety quickly before having to go pee.
Though likewise, I've also heard that having an apple (which helps you to wake up), before going to bed (especially as a child), will incur nightmares... But I can assume, at the very least that one would be awake a bit longer.
Also, you can "teach" yourself to be lucid whilst dreaming. That is, you can control your own dream while dreaming.
And not very dream related:
Thanks to Sol. for reupdating the bold topics, its always nice to look at some stuff discussed in the past, like the idea I forgot about, where we just write a plethora of maturely rated material.
And on that note:
Because I assume we are all crazy here, is there certain conditions or things that have to be met, before you can start writing?
Like a certain location for things, a certain drink ready at your disposal, etc. ;)
One definite thing for me (and I'd assume many others) is music... Even though I haven't been writing lately, I at the very least need music... and not a lyrical kind, but something without singing, so it is a little bit easier to concentrate at the task at hand... I'm not OCD about anything either, so it doesn't matter where things are, and I don't need a drink like coffee. XD
