Thank you for playing. Did you try examining and using the objects, e.g. using the bed to fall asleep? Then you can do something about insomnia (try to talk to Ana). The game is mostly about the dreams/nightmares that you will have while sleeping. Feel free to ask me if you are stuck. Once again, thank you for valueable feedback.
I used the toilet. So yes I tried examining objects but not the bed. Probably because there's too much objects in the game, e.g. I found a coffee machine, so beds are just among them and you don't think about examining them.
I got further in the game and it said: "You now remember the hyperdrive password", or something like that and then I went to the hyperdrive and it said: "You don't remember the hyperdrive password".
What you wrote about the hyperdrive is strange (I double checked and everything works correctly); if you try to hack the hyperdrive after you walked through the first nightmare successfully you should get the message: "You don't understand much about hyperdrive settings. Something needs to be done about it." Then you have to do one more thing to hack the hyperdrive.
Whoops sorry, I replayed and it actually said: "you remember your COMPUTER settings password". So remove "settings" from this text, people often get the relevant information and ignore the rest, I saw settings so I thought hyperdrive. So I got to the end ( I say that because the name of the game and the credits appeared on the screen and "end" so probably the end)
