Time Traveling Doctor

Date: 9/24/2019

The first scene was me taking notes at a university and studying to become a cardiologist. Cut to the future, I'm in a lab with one other doctor and there is a closet looking machine in front of us. We are arguing about who should go in, and we eventually decide I should. I walk in and the doors close immediately. It is dark and I try to open them but I can't. After a few minutes, the doors unlock. I open them to see a futuristic world (it reminded me of a realistic version of that one show that was like the Flintstones, but it was a family living in the future, I can't remember the name right now :/). Right as I step out a man wearing scrubs runs up to me and tells me they need me in the ER. We run into a hospital and into the ER. They tell me I need to create a robotic heart and put it in place of a little girls heart or else she won't survive. Then I woke up.
