This is a great first-person exploration title that has you travel through different dreams.  In each, you'll have a few objectives to complete to find the red crystal at the end.  It has that whole haunted PlayStation look to it (it was made for LSD Jam 2020, after all), which generally isn't my thing, and I still found the worlds to be visually interesting.  Along the way, you'll meet strange creatures, and some of the philosophy goes surprisingly deep for something like this.  Highly recommended if you're into this sort of thing.
