WILDs Keep You in the Same Spot, Initially? Or...

[Yume.no.ato]

During a WILD.... do you just lay there until you fall asleep, or are you supposed to imagine floatin gout of your body? I keep hearing different things and a lot of them have to do with still being in the same room when you enter a WILD. I thought it was just another way to enter -any- lucid dream world but now I'm not so sure o__o I've read a lot about it but I still have trouble understanding exactly how to feel or what to think when attempting it, which makes it virtually impossible to use. Also, I've heard that Sleep Paralysis is necessary to enter a WILD. The only thing is, everytime I expereince sleep paralysis, I see images of aliens or something terrible, accompanied by having a very hard time breathing, and sometimes it feels like I'm convulsing (if I've just woken up, say... my mind is concious but I cant open my eyes or move so in an attempt to shake awake it looks like I'm having a seizure). Is it really necessary? Cause if thats whats likely to happen, I'd much rather not WILD... ;__;
