So yes there are definitely limits on how much processing power our brains have.

And yes DC's are definitely fascinating and interesting.
I would say that there is an inverse relationship between the number of DCs you can have and how intelligent/clear they are. For example, if I were in a dream with my dream guide (witch happens a lot) it will generally just be me and her, and I can see her very clearly. But the more DCs there are, the less clear each DC can become. So by the time you get to four or five, each one may start to lose a definitive personality and appearance, and by the time you get into the double digits, your brain basically 'renders' them as a single entity.

The tricky part would be to increase your brain's 'processing power' to have more and more vivid dream characters.
