Yes, this happens quite often for me. What is going on is that you're quite aware that you have "control" over your dream but don't actually realize you are dreaming, you except it for reality still. The BEST way to solve this problem is to perform a reality check. This gives you full lucidity and makes you aware that you are indeed dreaming...whenever I don't do a reality check but become "lucid" and know I now have control of the dream, I never fully understand that it's a dream or have total control unless I convince myself otherwise with the RC. It's quite annoying when you just get excited and forget to RC and then end up in this weird situation. -Chase

P.S. There is another form of this where say, something is chasing you and you know that by leaping up into the air you can get away but you don't know that you are dreaming nor are you lucid so to speak. I've actually been trying to figure out a solution to solve this issue but can't seem to find a solid cure as of yet.
