WBTB + WILD.
I don’t do either of them like the guides here say you should, though. For WBTB, I don’t have an alarm clock set; I naturally wake up in the middle of the night. And I don’t get up at all for WBTB. I just open my eyes for like five seconds before getting back to sleep.
For WILD, when I’m falling asleep, sometimes I can feel how close I am to sleep (I get more lightheaded and have more random thoughts than usual). From there I… kinda focus on my head and listen to the tinnitus (that ringing noise in your ear). Usually, I can slip into a dream pretty easily. But it’s terribly hard to explain…
Though lately I’ve been trying out this technique. It seems fairly reliable…
