I honestly don't know as though I have ever made any distinguishing difference between the two, and I really don't know if there are other than we have disorder A and that disorder, when applied to our surroundings, produces unreality, and when applied to self produces depersonalization. I think there is a common thread, a source to it all - and it's a matter of direction - to what it is directed - that produces one or the other.
I say DP a lot, but that's simply because depersonalization/derealization is harder to say and DPDR just feels weird to write.
