Yeah, I don't have a division between the planes unless I choose to. I can separate them, but it's just as easy to keep them together. I think of them as the "inside" and "outside" planes, the only major distinction between them being that other people can only see things in the outside plane. They're not separated in position unless I want them to be.

For what it's worth, I can also hear them. I carry on conversations with people who aren't physically in the room all the time. For example. (My doc assures me that this is fine as long as I know they're not in the room and I don't trust what they say without verifying!) It's extremely useful for bouncing ideas around, even if it's really only an elaborate way of thinking about something by myself in several ways. I find it intuitively easier to discuss something with another person than just to sit and think about it.

I will say it's not much of a tactile sense, though. I can use my hands to manipulate things if I want, but I don't feel them nearly as clearly as I can see and hear them. I guess I also just don't do this as often, because how something physically feels isn't usually terribly important to me. Same reason I look at and listen to a lot more things for information in the outside plane than I touch.
