the whole "too good to be true" act.
here it is,
If you're in a dream, and your sitting in a hot tub filled with naked celebrities (whatever gender floats your boat) and you're sipping on a very expensive energy drink*, then you know your dreaming. This one does take more skill than the one I posted in my intro topic about the ipod, but since what we are doing is dreaming, it won't be hard to see something that's different.This is much like the reality check, or possibly the same. an average day would go by, you go to work or school, come home, do whatever you do(sports,computer,outdoor games,cleaning), and then at night when your going to sleep recall everything you've done that day. then think of all the things good that could have happened. after you think of what could of happened, go to sleep, thinking about the day still. when you get to sleep, and you are doing something out of the ordinary (ex: you woke up in a bed filled with cash) you should realize you're dreaming!
this technique is not my best/most used way, but it could help you all.
*had to change it from alcohol because someone complained about it promoting alcohol.
