i had a dream of subnautica gameplay, but the player wasn't in an actual biome. they were on land in a weird dimension that looked like xen from half life, but green.
Dreams about playing video games often represent a desire for escape and an opportunity to engage in fun or excitement in waking life. In this dream, the player being out of an actual biome and on land in a strange dimension may suggest an elevated level of curiosity or excitement for exploring new territories and experiencing uncharted territories in your waking life. The fact that the dimension looks like Xen from Half Life, but green, may indicate a sense of familiarity mixed with a sense of the unknown. It could be suggesting that you are comfortable with what you are currently exploring or experiencing, but there are still new elements to uncover that will bring a new experience for you.
