I have had a similar experience when I was 20. I was in bed asleep but woke up to what felt like a cats paws walking across my body. I could not open my eyes or move my body but I was fully awake. I was terrified and it lasted about 15minutes. Once I calmed down I was able to open my eyes and move my fingers and then slowly regained the ability to move my muscles. It was a very strange experience and it has not ever happened again.
