Many dreams can be quite lucid, therefore the dreamer may have the sensations from the dream, be they painful or pleasurable. I am guessing this is
what happened to you. Your brain gave off the signal that you had actually been wounded but in reality you had not, hence the leg cramps.
*Also* there are times when you may hurt in your sleep(leg cramps, belly ache etc..) and then slip into dream state and dream of something that is
triggered by your physical pain.
