I've been trying to do WILD lately, but I keep running into the same problem. Once the hypnagogic images/sounds begin to take shape, my body starts to spasm and twitch. I'll notice a few slight twitches of my arms and legs, and as I get deeper into the hypnagogic images, I'll usually snap out of it. My whole body will spasm and I'll jump and be awake.

Does this happen to anyone else? If it does/did, how did you get past it?
