A resounding YES!

You're thinkin': How does a person know if they're crazy
or not? Well, sometimes you don't know. Sometimes you
can go through life suspecting you are
but never really knowing for sure. Sometimes you know for sure
'cause you got so many people tellin' you you're crazy
that it's your word against everyone else's.

Another sign is when you see life so clear sometimes
you black out.
This is your typical visionary variety
who has flashes of insight
but can't get anyone to listen to 'em
'cause their insights make 'em sound so crazy!
