What...could this dream mean?

Okay, so, I woke up from this dream about a...game. That my brother was playing on our computer. And it like had this group of teenagers and gets really chalanging after the first space battle or something. It was strange.

I SWEAR he didn't own this game when we were kids, but......it feels so much like i've seen it before. Maybe in another dream. But why would it be so forgotten up till now?

I can't figure it out..

Being a teenager was challenging, and sometimes it seemed like a constant battle, and yet it seemed like a game - not real life like, being a teen perhaps you were spaced out or alien(ated) or it seemed so surreal like a game in outer space. Some of the issues you used to have perhaps you can now not quite recall, like they did not really happen, and yet you have vague memories.
