Couple of things fixed this for me... Temp fix is turning into a vampire and then turning back gave me full control again of my character. The second thing was having the travel lantern mod installed was bugging the crap out of my character any time I would enter the black book realm. Can't confirm for sure the travel lantern was the only problem though as I did clean main files with TES5edit and also re-ran FNIS...so could be that as well
