I can be huge.
Or unusually small.
Kids use me daily.
Makes tales that are tall.
I can be real.
Or just a nice dream.
If you just use this thing.
Real - anything could seem.
I could be a monster.
Or an invention of times.
You can use me to think of ideas.
Or plot out huge crimes.
Without me, you're dull.
Just don't even try.
I just have one more thing left.
Do you know who am I?
