hello daphna, and welcome to dv. sounds like what brought you to lucid dream was pure chance, maybe your just a natural.

yes. there are multiple ways to trigger lucid dreaming. what you experienced was a dild or dream-induced lucid dream. witht his technique you basically figure out your dreaming by either doing a reality check or questioning the world around you and seeing something unusual for real life.

sounds to me like your off to a good start feel free to pm me with any other questions you may have. hope you like it here at dream views.

also, if you haven't already i would strongly suggest that you read the tutorial page and start a dream journal!
