For me it’s running. Any time I need to run I feel like I’m trying to sprint though a pool of molasses.
I get this too, also when I try to talk and it feels like my mouth is full of cotton wool.
I do know a way around this but you have to be at least mildly aware you are in a dream. I once punched a cement wall in a lucid dream expecting it to crumble to pieces. It did not, because I was expecting a reaction from the environment to the forces I was exerting on it. But there is no environment, and thus no reaction. The wall you arm everything is just the dream. The trick is to visualize the wall exploding when you punch it and then it happens. Or to take it a step further realize that you only need to visualize the wall exploding and it will.
There is no spoon.
