The most emotionally draining dream I had was of being in Epcot Center in Walt Disney World with my wife and child. I'm fully transitioned, I'm happy seeing me, and I'm holding my daughter while my wife takes our picture. I point to my wife and tell my daughter "go run to mommy!" and she runs over to my wife. I smile, stand up (I was crouched to be at her level for the picture), and start walking over to my wife and child.
My joy is immediately shattered. Out of nowhere, my male self immediately crowds me and yells at me, "What the **** are you doing here?! Nobody wants you! Get the hell out of here!" He then walks up to my wife and child and the three of them walk into the park as I'm left speechless and in tears.
I woke up crying when I had this dream and it still scares me to remember it now.

To make matters weird, my wife and I have no children! Despite that fact, the loss of them felt palpable.
