I watched this movie some time ago.
Actual info about plot:
There is a man waking up in spaceship/space station. He is awoken by an ex-girlfriend/wife(?). She asks him a couple of times if he remembers her (something had happened between them before going into outer space). I think a second guy wakes up too. No possible communication with any other station/Earth.
The movie ends by showing you that the first guy that woke up is actually the only one alive. Many years have passed since the time he thinks he lives in, the woman (who obviously isn't alive) and everything he sees in the whole movie, is the alternate reality a creature/organism/parasite/entity/alien (I really don't know what to call it) that has been living there created for him, as it could see through his memories and recreate them. Everything in reality was covered in webs. I think the organism is shown and looks kind of like a spider but in a cyberpunk way.
