Or maybe you are just hoping for a mangickal answer.
You are not shifting. With a forum title such as this it is clear that it is what you believe is happening, it is a common phenomena that when you want something to happen you often feel the side effects without any of them actually occuring.
The cuts and bruises can easily be gained by simply moving in your sleep, knocking into things, catching on things. The full moon is a powerful time for anyone interested and practicing the craft, it is probably a mix of this and your desire for something more supernatural to occur at this time. If you have severe emotianal changes or severe pain in arms and legs I would say it is best to go to a dorctor and get checked out, just to be safe.
I hope this helps somewhat, even if it is not what you were after.
