Stephen 
Tony left to go to his room and it brings a memory of what I looked like after my mother and then not a long time later how I looked when my dad died. Then shortly after that it was my siblings. 
I know Tony is just tired and I hope his PTSD doesn't affect him while he's asleep. I get up and wish everyone a goodnight before walking to my room. When I get there I get ready for sleep and set my alarm. 
I then send a text to Tony to explain my absence tonight. I then rest my head and fall asleep.
The nightmare 
I'm in my old house and I see my family sitting there. They look so happy and walk over to them and then things start to change. I watch as my mother change into her slim and pale figure she was when she died. 
I rush over to her. "No no no no no no!" I run to her and try to use healing magic on her but it doesn't work. I turn and see my dad's mangled body from what he looked like after the car accident. I know what's next and I run to my siblings. I see the blood start to pour from my broth Victor's head and then he goes limp. 
I then turn to my sisters Donna and the same thing happens. Everything fades to black and I look around for a bit more before a hear someone yelling at me. I snap my eyes open and see Peter inform of me with a worried expression on his face. 
"Wizard Dad are you alright?" He asks and I get taken back by the question a bit. 
"I'm find kid. Also did you call me Wizard Dad?" He looks a bit embarrassed so I ruffle his hair for a moment before laying back down with a sigh. A minute later Tony comes running in and hugs me with tears in his eyes. 
I sit back up and hold him close as he cries. I rub his back while whisper to him anything I can think of that will calm him down. After a bit he's calm so I lay down while still holding on to him. "Peter lay down. It's late and you need to get some rest." 
He looks at me for a bit before laying down on my bed and falling asleep. I gently lay Tony in the other side of Peter before getting up and pulling the blanket over them both. I get up and get dressed in my robes before walking out of my room and going to the kitchen to get some tea. When I get there I take a quick glance at the clock to see that it says 2:35 am. 
It's not unusual for me to wake up around this time since the times I failed or had to watch someone die shows up in my dreams every time I fall asleep. I leave a note for them on the counter and go to the sanctum when I finish my tea. I open a portal and walk through it to find the sanctum a wreck. 
"Wong?" I notice him standing in a door way with a look of horror on his face. He looks up at me and when he sees me he steps away from me. I stop at look at him confused. 
"DAMN IT NIGHTMARE I'M DONE YOU KILLED THEM ALL ALREADY WHAT MORE COULD YOU WANT!" Wong yells at me and I'm even more confused than before. 
"Wong who the fuck is nightmare?" Levi flies around Wong and pats him on the head. Wong calms down at the sight of Levi and then looks at me. 
"Stephen nightmare is from another universe. He's come here looking for you so he can drive you to kill yourself or murder others." Wong says and I can tell that me even being there is an issue. I know that Wong isn't big on hugs but I give him one before leaving. 
Tony
I wake up and find Peter next to me but Stephen is gone. I get up and walk out to the kitchen to get a cup of coffee but get distracted by a note on the counter. I walk over to it and read it. What I read makes me a bit upset but I understand. He doesn't have any reason to spend his every moment here. 
I grab a cup of coffee and then Wong shows up. "Wong what are you doing here?" He looks at me and asks 
"Did Stephen return here?" I look at him confused.
