I have almost similar dream as yours though not totally because in mine I didn’t come to go up and walk outside but the feeling that some like rocks in your chest?yeah that’s what I experienced a lot of times mate,there comes a time that I though seeing people around my bed and they seems talking while me is shouting but they can’t hear me.as in shouting loud for them to recognize that I need some help to move ,until I finally carry to woke up and find out no ones near me but myself and I was only dreaming.some of my friends told me that it is some kind of near heart attacking process that I came to survive

I checked my phone and there was a notification that I won an election, lol.  I don't know why but this felt extremely real
