Not so much a magic issue but more (I think) in lines with meditation. I have noticed the ability to make a few minutes stretch out to last around an hour. (No not literally) For example Every so often when I have to go to work and failed to get enough sleep. I will lie down for a few minutes rest. I will concentrate on relaxing and for lack of better words "holding onto a minute" While doing so it feels like more time has passed than actually has. Most times I go check the alarm clock thinking "ow God I've over slept and am late for work" (I need to have more faith in my alarm clock:p) Only to find that one or two minutes have passed.
Any way when I do this It feels like I've gotten an hours rest and I'm good to go. I have found that it will not work if you are listening to music or watching something that is continually moving.
So does anyone else have experiences like this? If you have not tried it I suggest giving it a try say before you would normally go to work or school. (Note try it 10 minutes before you would have gotten up anyway so to avoid being late)
