I remember once when I slept for about 4 hours per day only for a few days and I kept yawning, I lied down and just tried MILD'ing, I think about 4-5 minutes passed by and sleep paralasis was starting, I started feeling less and less control over my body, I was even moving my hands, then all of a sudden my whole body went numb and I couldn't even open my eyes even if I wanted to, I got to SP and got to the part where you feel like leaving your body but I panicked too much and it stoped after 30 seconds with a weird explosion sound, so I guess you could do that. =/

Oh and I only panicked because I never really readed about WILD at all. xD

Never really got to that point again though since I slept for more.
