Is it possible to create your own subliminal messages (both visual (VIDEO NOT PICTURE) and verbal (like an mp3), listen/watch it and have it work. Cause i have a game called LittleBigPlanet 2 and in that game you can create cutscenes with voice overs and i was planning to have the voice overs be subliminal hearing while the visuals be subliminal sight.

So, is it possible to create your own subliminal msgs and use them?
