I mainly created this post because I found a lot of stuff wich helps, but not that much about things that acctually decrease your chanses of becoming lucid. Do any of theese affect your chanses of becoming lucid?

* Playing videogames
* Using your computer
* Watching TV
* Listening to music
* (Doing any of the above right before going to sleep)
* Being tired (Very tired)

I appologuise if this subject has already been answered.

EDIT: Sorry for misplacing the thread.
