Hello everyone.

I woke up last night, on my left side, rolled over to my back and found I couldn't stretch out my right leg! ..well, I could, but it really hurt my knee. After a while I just forced my leg flat and stayed that way for a while and then it was fine. O.o

I did 2 reality checks, so I'm fairly sure I wasn't dreaming.

..anyone any idea of what this was? Can muscles cramp up that much, or was it an effect of SP? I'm very experienced with SP, but I've never had this before..
