Having studies a bit of psychology in my time, I would probably disagree with some of the posters who have guessed that this may have been the dream
manifesting itself physically to cause the pain via the subconscious.
A more likely explanation is that you hurt yourself in some natural manner - ie you bumped yourself (just giving an example!). Then, whilst you were
asleep, the dream state incorporated then pain and came up with this strange scenario. So I'm kind of coming at it from the opposite perspective as
some of the others.
Or perhaps a bed bug of some sort (hey, it happens in the best of families!

).
Such events happen all the time: the dreamer incorporates physical impulses, reactions etc. and merges them with the dream imagery.
I remember numerous such occasions myself. Once, when I was a child, with fever, I had a hot water bottle at my feet. During sleep I somehow caused
the container to open, so the water flowed out, inundating the sheets around my feet. I vividly remember dreaming - all of the sudden - that I was
wading barefoot through deliciously lukewarm puddles in the garden.
On another occasion, a dream of mine was suddenly interrupted by an apparently incoherent image of myself smelling flowers in the garden, and then,
with no intermission, I found myself in a Parisian perfume store, smelling perfumes.
When I awoke, I immediately smelled one my mother's perfumes in my room. She had come to see and kiss me while I was dreaming, leaving her fragrance
behind in my otherwise odourless bedroom.
And those are only the NICE ones!
