My Own Unmanned Aerial Vehicle (UAV) & Turning Into A Titan To Defend Against Titans

I barely remember part of one dream that took place during a nice day in the city of D, and at some point I think that I was with my brother GC and/or one or more people outside.

I either found or bought or was given a mostly whitish colored remote-controlled toy airplane that had a camera on the front of it that someone added to it, and it was basically a custom-built unmanned aerial vehicle (UAV) that you could control and see what it sees.
