EVERYONE dissociates from time to time... it is very common for drivers, for example, to be in the driver's seat and then realize they missed their exit OR that, wow, I got here fast... it is also called highway hypnosis...

When we daydream we can dissociate...I mean, often that's why we daydream, to get out of "this" reality and imagine something more wonderful.

Having a disorder that includes dissociation just means to me that instead of being able to deal with a situation, you find another way to deal with it... handing it off to another part of your brain?
