Attaining lucid dreams with a 9 hour long mp3?

[Mond]

Even when you sleep your real bodys senses are functionating in the reald world. You can hear the sound of your environment, or can smell etc. Nova Dreamer LD machine (which is can sense when you dream by eye movement) use light and sound to make you realize when you are dreaming, however with a little math and testing its possible to create a simple 9-10 hour long mp3 file, which is containe a message what is warn you when you in a REM session. REM sessions approximately occurs in the same pattern, after the same amount of sleep. So it can be count out when you need to put a sound message into the 9-10 hour long blank file. This file is can be created with a simple music maker program. Well at least this is the theory. A 9 hour long mp3 file with a 128 bitrate quality is about 420-450 MB (if i counted properly) so its possible to put on even a older mp3 player. (sry for the bad english)
