I'm a space cadet, an astronaut,
On several occasions Future has stated that he’s is an astronaut — Future uses this a theme in his music. He has an mixtape named “Astronaut Status” and his debut studio album was named “Pluto”. Also, he has a song called “Space Cadets”, on which he also calls himself a rockstar (see next line).
Future uses this theme/metaphor to describe how high he is — always influenced by drugs.
