I had something slightly similar to this:

I woke up from my sister making a bunch of noise, so I shouted at her and got kind of mad. I fell asleep with this anger attached to my emotions.
I had an extremely vivid dream, which I had a false awakening to my sister making more noise. I got up and went over to hit her (I never hit her so I'm not sure why I did this). However, when I hit her, my arms felt like jelly.

This may be similar to what you were talking about with the SP bleeding through. It hurt to move my arms, however, I felt no soreness when I got up.
