often times when i'm about to go to sleep or waking up in the morning and going back to sleep, i experience something that can only be described as a shock throughout my entire body. it's not really like SP or HI vibrations or anything like that (because i've experienced all that before). it's just a quick little pulse of energy/shock all around my body. it isn't exactly unpleasant but it doesn't really feel good either. anyone else experience this? it usually occurs even if my body isn't entirely still, which is why i don't think it has much to do with SP, HI, etc. although i could be wrong... thanks!
