Little Manipulations of American Comics

Writing idea: When I wake up, I travel back in time, and when I sleep, I travel back in time. Here comes the problem. When I was sleeping, when I traveled back in time, I was in bed, sleeping all the time. Wake up and travel to the universe where you are always awake. The protagonist becomes a human being who has been awake in the universe he traveled to. So let's talk about where I traveled through time. American comics? Yes, yes, DC and Marvel plus a bunch of American movies are integrated into one universe!
