I mostly do that too, but I can switch. For example, to trying to process everything visually, perhaps wandering through familiar places in my mind (or listening to familiar voices/songs).

Or you can turn it all off and focus entirely on your senses themselves. This can be interesting when, for example, you imagine something in contact with your body as a part of yourself. Do that to your car, for example, then you start to pay more attention to exactly how your wheels grip the road and you have a more intuitive feel for where every part of the car is in relation to you.
