I think I have a solution to all the gamers out there...
Well, if your like me and love to play games all the time then you might experience lots of video game dreams. I know I do...and since I already know games are fake (some games are made for the realism like WWII games or whatever) I seem them as something normal and won't have to question.
But if you notice in your dreams you will see things from all different types of games you might have seen or played.
Just last night I had a dream about Final Fantasy XI, but it was some different game that was similar to it but the buildings and enviroment looked different. There was also a building I was supposed to go to (It had some special name but I forget what it is) but when I got there I was attacked by zombies and was outnumbered. But that's a different story.
What I'm trying to get to is if you play games like Half-Life 2 DeathMatch, Counter-Strike: Source, Day of Defeat: Source, or any other game that allows you to make a custom spray and and spray it on a wall (usually to taunt other players or to be funny or something) then try making a spray that says "You are dreaming! Do a Reality Check!" or something.
Now, I do not know if this will work 100% of the time...I just thought of this today and figured other people should try it as well. It might work for some or it might not.
I wouldn't know what to call this technique (if it really needs a name) except for Game-Spary Induced Lucid Dream G-SILD (the dash makes it look cool). In other words, make a custom spray that says something along the lines of "You are dreaming do a reality check!" and spray it ingame every so often and ponder at it or question it or something.
Also, if your game does not allow custom sprayed images, then it might allow you to change audio files. So if there was supposed to be background music, try replacing it with a lucid dreaming induced MP3.
You might also try "skinning" one of the models in the game. Skinning is when you take a prop or model (Like a gun for instence) and make the colors look different.
I hope this helps some people out and I hope it helps myself out. Some might say that I should probably find people for testing and gather information and stuff first but I don't have the time to do stuff like that and I would also be forcing people to play video games when they should be doing homework or something...I'm just saying that as an excuse so I won't actually have to do that...
