While trying any kind of sleep-typing, you probably want to use a keyboard like this:
This keyboard is missing every key that lets you delete words you’ve typed or otherwise send commands to the OS or text editor/messaging program you’re typing in (Ubuntu+ion3 and irssi here — your mileage may vary). When you drift off to unconscious sleep, it’s very easy to accidentally delete text, close the program, or other such counterproductive things.
It can be difficult to try to study something that by definition screws around with the thought processes you use to study it (I’m sure scientifically-minded drug-experimenter types would agree). But I have definitely had dreams where I was able to do some sciencey stuff while playing around — examining the simulated world to see how detailed it is (I wonder what rendering engine my brain uses …), testing what I can and can’t do in it, and so forth. Inevitably, since dreams are so hard to remember, I forget about the allure of the whole thing for long stretches of time. But eventually I have another vivid dream and start thinking about the possibility of playing around with a complete, realistic virtual world of my very own, and my inner SimCity player insists that I try it again.
Since dreams are so intangible when one’s awake, I don’t think that there’s any way for them to become a serious enough interest to detract from real life. But they’re a fascinating phenomenon and I’ve had fun when I’ve played around with them.Â Also, a few nights ago I had a long dream where I spent a lovely afternoon with Janeane Garofalo. And when the negative results of your experiment are “a lovely afternoon with Janeane Garofalo,” you have a good experimental design on your hands.
