Don't worry so much about control. For now, just walk around and enjoy the scenery. I've noticed that the LDs I do not control both last longer and are very realistic.

I had a 30 minute long one about two weeks ago in which the only supernormal thing I did was fly. I was amazed at the clarity of the dream. I could hear the gravel crunching under my feed as i walked down the road, I could feel every single blade as I flew low through some tall grass.

Control will come later.

Congrats on your LD!
