A long time ago I had a dream where I was walking home from school. Out of the blue my street became a cricle, and there was no way for me to get out. I kept walking home and I saw a pack of about 20 dogs eating something. Now I don't like or hate dogs, but this made me uneasy, so I started walking the other way, since this street was now a circle I knew I'd get home anyways. So as I'm walking I see just one dog... it is chained up. He walks up to me and for some reason I am more scared of this one dog than the pack of dogs. So I turned around willing to take my chances with the other dogs when the dog that was chained up tells me...
"No corras por que la cadena es larga"... ("Don't run because the chain is long")... so... I ran. I was terrified and worse of all, the chain WAS long. I ran for about half a block and he was still behind me. Suddenly I stopped, and said... "This is a dream" I turned around and the dog jumped at me, and just as he was about to bite my throat I opened my eyes.

Back then I didn't even know about lucidity I think I was 13 when this happened.
