Someone who just spaces out all the time, usually when they should be doing something productive instead.

Spacey. Spaces out and says things that are totally random. Someone who is not following what is going on because she is busy thinking about photography.

The space cadet is often lost in their own thoughts deeply pondering something but they cannot verbally explain it to others so they often seem spaced out of conversations and ditzy. Meaning others mistake them for not being as hyper aware of their circumstances as they really are.

The space cadet has the potential to say profound and often thoughtful things when given the context of what they missed. The space cadet misses key moments in conversation while trying to think with their full cognitive focus.

This person frequently thinks of far greater in scale things than their current surroundings, like a cadet examining the magnititude and complexity of space. When the space cadet returns to earth, they have such a unique and often unrepresented perspective to share.

The space cadet likely rejoins the conversation far later than they intended to and the subject has changed since then so their thoughts seem disconnected from the current conversation. The space cadet may be so lost in thought that they do not respond to their names or notice others attempts at getting their attention.

The space cadet may also finds themselves naturally drawn to using medication or weed due to how it helps them relax their overthinking and zone out into deep thoughts.
1."Dude ____ stopped responding 2 minutes after we started this conversation."
2."I bet ____ has already lost focus on what we were talking about."
1. "They are such a Space Cadet, I wonder when ____ will return to earth and reply to this".
2 "Likely after the high wears off. ____ zones off so much and loses track of their of thoughts when they try to explain what's on their mind".

1 "Idk why ____ does not just try harder to speak clearly and stay focused on the conversation. I always have to explain what has been happening or what they have said since they zoned out.".
