A yellowish-green gelantious unknown - annoying: This has been something that's been going on for about 2 years by now and it's extremely annoying. While I'm sleeping, there's about a 10% chance each sleep-wake cycle of mine that this will happen. When it does happen, I'm otherwise forced to wake up and take care of the mess. What's the problem? I wake up to a sticky, yellowish green (hue 100°, saturation 70%, value 80%), gelatinous substance in my underwear. I've been thinking I'm piddling in my underwear, much like 1-year-olds often do (only in diapers). I have no idea why this is happening. How to stop it? That I don't know either. At least it's rare, but I would like it to stop. I don't know what's different that I'm doing that's causing this to happen.
