Does Reality Exist?

First thread of the year, let's go.
A hard question to discuss but worth a try. The question arises due to the fact that we don't know if anything outside our perception is real. Has anyone ever question this? How did you come to the conclusion that the people/things around you aren't just a part of your imagination?

reality is real. proof: you can't make this shit up

Stupid thread is stupid.

I stink therefore I am.

Our brains break down color and we therefore are able to separate our reality through color. Reality is our cognitive construct of what we see and hear. I am sure if we were to see through high definition frequencies we would have a different perception of reality

Isn't existence the definition of reality?
