Hello, I have a few questions on how to keep my lucidity, even if it's a little.

I manage to do a RC in my dream last night and became semi lucid.(I was in my bedroom) I was exicited that I ran down the stairs, looked at my front door. Pressed my head againts it and the door got fuzzy and dissapered. I manage(first attempt) to walk through objects.

I ran out to the streets. And a DC came up to me and started talking to me and then I lost lucidity. I mean. I lost it FAST. And then the dream faded.

Any idea how I can keep my lucidity? Avoid dcs? Or etc?
