You were told to never go to Pennywises true dimension by Maturin as Pennywise doesn’t follow concepts in this dimension

You entered this infinite dimension and noticed that it’s an infinite void full of evil and darkness. You see a giant female like spider clown move at you at speeds faster than the human mind comprehend

You then see Pennywise transform into his true form which is a size infinitely bigger than you

Pennywise: You are so naive and uneducated human
