What makes something real?

Is it the fact that i can use my senses
to confirm its presence?

Confirmation of this from another source maybe?



How do you know that tree is there?

Because it is

How do you know?

I can see it

Are you sure?

Yes
Hey Frank
Can you see that tree

Yes

See
There
Thats two of us
It must be there

Well what if you're both wrong?

Fine
Bob
Come here
Do you see that tree?

Yes

Ok
That's three of us
The **** tree is definitely there
Right?

Well what if Bob, Frank and yourself
are all falling for the same trick?

What if the same trigger sparks the illusion for all of you?

What if the whole planet is a tree?
What if our whole existance is a tree?

And we're just a bunch of Bob and Franks
