The Premise:
You wake up in a strange place. No memories of your past life, not even your real name. You are alone, with only a blue sky and a green ground to keep you company. You wait, and wait, hoping someone will come and explain like in the movies. Maybe tell you you're trapped, yet you can walk anywhere you want. The ground is flat. The sky never cries.
Naturally, you start wishing for things. Food, water, shelter. The necessities at first. It all appears, everything you want becomes a reality. Nearly too good to be true, which it is. Everything you wish for is basically synthetic. If you wish for food, it is sustainable but has no distinct taste. If you wish for people, they aren't really PEOPLE. No emotions, no needs or wants... It becomes creepy, even boring. Maybe you even start becoming delusional, until the loneliness nearly consumes you. When this happens, a path opens up for you to meet the others. The others who have been here. For days, weeks... Maybe even years?
It's not perfect. It may be everything you wish, though it doesn't feel REAL. Additionally, strange things begin to happen. Why is that type of food there? You didn't wish for it. Why are some of your desires not being granted? Why are those synthetic humans randomly appearing? And turning into MONSTERS!?
