please check grammar usage of the following.
if you don't mind me asking
if you don't mind my asking,
and another one
had a dream of me facing impending doom
had a dream of my facing impending doom
The second two are also grammatuical, but the second is a bit odd. The dream was a about a person in a certain circumstance. #1 fits that sense much better. In the second, the dream is about "facing".
