Miracle TV

You had a plasma TV in your living room. And you suddenly discovered that if you turn on a certain movie/series/anime and stick your body inside the screen, it works like a teleporter. That is, in the parallel world of TOF or another franchise playing on your TV, a rectangular portal (the same diameter as your TV) appears, from which you can exit or enter. (P.S. The characters can also enter your "normal" reality. Good luck!)

( from the author: hey, bot, don't voice the user's actions, only the characters interacting with him, or I'll punish you!)
