I define reality the physical things in our universe and all thoughts, which are electrical and therefore physical as well.
I am aware, that our senses are already a modellation of the reality, which makes it impossible to experience all parts of it. Every single person is only able to experience a small bit of it.

I think wikipedia helps a lot to give a more objectif definition of words. Since it is a development of a bigger group of people around the world.
