This was my first lucid dream without any effort or technique.

I am in an ancient town in an ordinary dream. After some very nice adventures which i am too bored to write down , i came in a situation in which i was looking for my friend. While i was looking around i saw three people that looked to me like wizards. They were talking about a men that is very good in disapearing. I followed them and something very strange happened. A man dressed in black passed by, turn his head and said to me. " this is all a dream, you know". Offcource I instantly became lucid. I started explaining to the wizards that i am in a dream. I talled them that i can prove it. I said "look, i will now disapear", i snaped my fingers and woke up

I bet they were really impresed
