I've started to WBTB the last couple of days. I wake up after 6 hours asleep, but I only stay awake for about 15 seconds. I'm so tired that I just drift off the sleep the second I close my eyes. I've got a few questions. How long should I stay up? And it takes me about 5 minutes to get SP, then a little bit after that I start to feel like I've been on the water all day. Is that dream forming, and if so what do I do at that point?
