I’ve tried everything but I can’t seem to find this particular movie and it’s driving me insane.

It’s about a man who invents a doorway/portal to a parallel universe in his basement or garage. I think that when the portal opened, he saw himself. It’s night time. They’re both excited it worked and leap over to each other’s world. “Our” man starts exploring the other house/world and at some point some strange ritualistic sexual stuff starts happening. It’s all very ominous. It seems that men in the other world have weird, deadly sexual organs. When our man finds out, he suddenly thinks about his wife, who’s asleep in his own world. He rushes back but finds blood on the walls of the hallway and the bedroom. It implies his other self murdered his wife.

Now that I’ve written this all down I’m really hoping this movie actually exists and isn’t just some figment op my imagination.

Thank !
