Once you try VR its very easy to realize the potential for this. I think for the next version of the prototype I'm going to drop the Kingdom Hearts angle, as it didn't excite and motivate non lucid dreamers to try it out as I had hoped. However InnerVision gave me an idea...

I suppose its true that performing a task in VR makes the experience more immersing than if you just sit and stare into the environment. Maybe the software would work even better if you were preforming some sort of common simple task over and over. Like walking through a door... I also suppose this software could frequently remind you to perform a reality check once crossing the doorway and remind you that the environment is associated with dreaming in predictable intervals.

So if you do this task a few dozen times every night before bed with the intention of retaining it in your subconscious it should increase the chances of you successfully becoming lucid. In theory, over time you should be more likely to see a door in your dreams, walk through it and perform a reality check.

But then again, you could do all this with a real door. Maybe there was something even more profound you could simulate in VR than walking through a door? I don't know...
