Hey Electrix,
You should be able to activate the space dream via the dreamer app on your ingame phone and then select it from the dream list.
The schedule is as follows for releases: The Alpha build of a new version is released at the start of each month. About a week later the Beta build is released. Then after another week the Early Access version is released. Then about a month later this version goes free and public.
This is the Patreon schedule, so it drops on Itch n everywhere else a bit later on.
Hope this helps!
