I have that with nightmares sometimes. I wake up bathing in sweat ,waking up from things like an extreme sense of falling/about to hit something etc that really scare me awake. And usually no recollection of what I dreamed about...
I had a nice nightmare last night, and I only remember the last bit where I had to descend from a mountain that was made entirely from a steel bar construction like used for reinforced concrete. I really was so soaking wet from sweating that the smelly sticky wetness had woken up my wife and made her go out of bed early
