I had this dream exactly a month ago: i was with some friends complaining about something while i was trying to push my fingers through my hand and one of them told me it was a lucid dream, so i tried to convert a cardboard picture of an ice cream into a real ice cream and it worked. Later in the dream i was in my room, i looked at my watch and the numbers were changing (the hour was something like 30:57). I moved a little and tried to jump to see if i floated back, but i didn't. Then i looked myself in the mirror and the colors of the dream changed to sepia and black & white. I tried to control them and they returned to their normal color. Then i told myself "this is a lucid dream". I remember the door was open and i looked outside, my mother was standing in her room looking at me. When i woke up i asked her if that happened and she said no. I did 4 reality checks, my friend told me it was a lucid dream and i told it to myself later, why didn't it work? I'm so frustrated because it's the closest i've been to a lucid dream and i have been trying for more than 2 months!
