Dreamt of my wife

A few months ago I had two dreams of my wife in the same night. I was dreaming I was walking through a very large house where a party was going on, then I saw her from behind. I walked over, put my hand on her shoulder, and said "I can't believe I found you". She turned around, and boy she was pissed, she said "stop looking for me, I can't come back". I sat straight up in bed, covered in sweat, my heart was racing. I have no idea how long it took to fall back asleep because the next dream I was in bed. She walked into our bedroom looking sad, and said "I'm sorry I yelled at you, and I know you miss this". Then she got into bed and let me hold her.
