Well... I don't know if it's the same thing. But I quite often find myself experiencing emotions (anger mostly) that I don't seem to be able to control. I'll be in the midst of a fit of anger over something. I know what I'm doing, or how I'm acting. But I don't seem to have any conscious control over it. It's sort-of like I'm a bystander watching someone else's hissy fit! So, in that sense, I guess one might view it as experiencing someone else's emotions. I guess I know they're my emotions. But I don't seem to be able to exercise control over them.
