Dream Machine

Dream Machine is an interactive fiction that was created during SunJam 2018 by Jed May!

You wake up in a strange metallic room. There's not a trace of who is doing this, where you are, or how you even got there in the first place.  All you know is that each time you approach that door, strange scenes take place.
