My DS is all of a sudden waking up at 11PM every night for last few weeks screaming.
We have to go in there and rock him to calm him down. We have tried just letting him be but he screams so hard we cave and go in there.
Could this be nightmares? He is going down awake and falling asleep on his own.
He also has had a slight cough and some nasal congestion but I highly doubt that is causing this night wakening.

"When it comes to sleeping, whatever your baby does is normal. If one thing has damaged parents enjoyment of their babies, it's rigid expectations about how and when the baby should sleep." ~ James McKenna, Ph.D., Mother Baby Behavioral Sleep Center, University of Notre Dame
We've had similar things happen twice.
#1 - DD kept waking up around 10:30pm, terrified. Would refuse to go back to her bed and eventually fought going to bed at all. Finally, one night we were sitting with her by her bed trying to get her to go to sleep and the 10:30pm time came by. A huge truck went by. The lights (we didn't have shades up yet) came right in her window, plus the "strange", loud noise. That's what was scaring her. We explained to her what it was, got the blackout shades up ASAP. Problem solved.
#2 - DD started waking at 5:15am, nearly every morning, wanting to get up for the day. I'd usually convince her to crawl in bed with me and could get her to finish sleeping in our bed, but she wouldn't go back to her bed. We finally figured out that she was hearing DH's shower as he got ready for work. DH started shutting DD's door when he got up (we keep it open overnight), and shut the bathroom door, to drown out the sound. Problem solved.
I think as they get older, they just start becoming more aware of their surroundings, and if they're not in a deep sleep, then these sounds & things really interrupt their sleep.
Hope you figure it out. Whatever it is.
GL!
