Just a small sampling of what I've experienced via empathy:
The pain and other emotions of critically injured soldiers at a military hospital near where I used to live (possibly one of the worst).
The "dust" left over from a murder in an apartment I was going to rent (good thing I didn't).
Exactly what happened with the USS Lexington. That was fun, going up all those stairs, although none of us could bear to go into the main engineering section.
When my friend's child was born (a mix of emotions).
When my neighbor upstairs gets high as a kite, and when the ones nearby fight.
The terror of a death row inmate (ugh!).
I don't mind having this gift but sometimes I don't know how to shield myself well enough so I don't go to pieces and guzzle a massive pot of coffee at the first opportunity.
