This night i think i had my first Lucid dream. I remember having one “normal” dream and then i woke up, after some minutes i fell asleep again and kinda instantly found myself in a dream.
This time i was lying in my bed, and for some reason i felt instantly “This feel wierd, it must be a dream or something” So i went up and i looked up at my wall, My wall is covered with Gaming magazines covers, like a collage. I started to look at the covers and i remember one cover that had the headline “Terminator is Swedish” but when i looked at it in my dream, there were no letters at all on the cover. I turned around at watched it again, now it was just jidderish and i could not understand what it said.
At this moment i was getting pretty sure that i was dreaming but i decided to pull off another test. Around my wrist i have these Festival-wristbands but when i was looking at them one of them is suppose to read “West Coast Riot Festival 2008” but now it was saying “Call of D…” probably refering to Call of Duty as i play it often.
I was now sure that i was dreaming and i went downstairs where it was total chaos. It was things and boxes everywhere, like someone was about to move to another house. Here i got the idea that i wanted to go out and try to fly. I started to look for some cloth assuming it was cold outside. I found a sweater and went outside, on the way out i went by an mirror as i looked in. I saw myself, but very deranged and i was really frightened and felt as i was about to wake up.
As i got outside, the first thing that happend was that something fell from the roof only some feet away from me and again frightened me, here i was getting really exicted i felt like i was looing it. But i told myself that i wanted to fly, as i was about to try, one window of the house blew open and a big machine gun appeared 
This freaked me out, i knew i was dreaming but still i was really frightened, i ran away and calm down and now i actually did fly. And i just like, jumped and away i went but here the exictement became to much and i woke up.
The strange thing in this case is, alot of the things that happend in the dream had happend during my day, and was not really ficional. Like the Magazine covers, before i slept, i actually watched them abit, and the festival-wrists, i often just for looks sake try to arrange them in order just to look good, i do that everyday dosens of times. And the Call of duty thing is pretty obvious since i play it often.
But my question is, was this really an LD? Since i really felt like “Hey,I’m dreaming now” But still i did not have full control, and everything were not that clear and bright as everyone says, it was kinda blurred.
Sorry for my wall of text 
, hope anyone wants to read it.
). And also, you were not certain that you were dreaming even after the posters in your room were different than how you know them, that’s quite a big clue! 
Anyhow, im no expert at all, so this is just my speculations and ideas!
Let this dream serve as motivation and Im sure you will be successful soon enough!
