This isn't posted in my dream journal as I had it about a week ago and hadn't found the forum yet.

I was in a house that was also a museum. I wasn't supposed to be there, as it was a private residence, but there were several paintings and interesting artifacts and I had snuck in to look at them. After a few minutes, I noticed my hands and realized I was dreaming, so I decided to float up and zoom around the place.

It's been a while since I've had an LD or practiced flying so I was a little nervous and my technique was a little off..I kept sort of bumping into the walls. Then the man that owned the house came in and I realized that if I stayed near the ceiling, he wouldn't see me. Around this time I think I started to lose a bit of control and get too excited. For some reason the thought crossed my mind that I couldn't stay levitated if he happened to see me and right then he looked up. Once he looked at me I fell to the floor, then I had a short FA and was not lucid in that one.
