Ok, first off, if you really wanted to experience two LDs at once, thats not the problem. THe problem is being conscious of the two simultaniously. Your conscious mind can only percieve or process so much, I think its like 7 bits of data at one time. It's your subconscious mind can process all the other stuff.

Being two people at once would be an overload on the conscious part of your mind. Sure you can do it subconsciously, but being two conscious people... it's just not likely your able to do it. I mean for instance, try splitting yourself up into 10 people. Your mind can create those ten of you, but you can only control one consciously at one time (if each one is given a unique command).

If this were possible, you'd be literally creating a unique conscious being.

One thing you can do is, consistently switch between the two at the high points of the LD experiences. I think you can do this effectively to where you would get that effect, but once you start going over 2 of you... it gets to be just switching between people.

Now the split screen.... isn't necessary, and if you did that, you'd probably be splitting your body in half as well, unless your seeing yourself in 3rd person.

Thats just my opinion however, based on what someone can be conscious of all at once. (think of it as trying to be conscious of the whole universe, you can see it as one big picture, but being aware of all the detail at once... doesn't seem possible).
