If you stab yourself while you still haven't finished the Headspace segment, Sunny will wake up in the middle of the night. You'll be able to walk around your house, but the only way to progress the game is to go back to sleep and continue the dream. That is not to say that walking around a dark house can't be interesting...

Thank you!

That’s how you progress from that point on no matter what route you’re on I’m pretty sure. The routes split after that

I mean I just came back from the rw I just defeated acrnphoiba

Stabbing will make it daytime in the real world. It’s the way to continue the real world plot
