More Than Meets the Eye

Nothing is as it seems.
You have to know that,
In order to believe.
People are not as they seem.
One moment, someone will be kind,
One moment, they'll be cruel and heartless.
Places are not as they sem.
Although it reads Bowling Alley,
It's really a bar.
Things are not as they seem.
It looks like something you've seen before,
Although it really isn't.
Ideas are not as they seem.
As you think of a meaning of something,
You're told your ideas are inaccurate.
Because, I told you.
Nothing is as it seems.
Now read this backwards, from bottom to top, and see if it makes any sense.
