Hello my dear! Dropping by to say hi. We often perceive the antonym of normal into abnormal. It is good that you still used the compound word "not normal" pertaining to its counterpart. Not normal would depict as something that is beyond what we are used to. If it's beyond normal at its superlative sense then it becomes para-normal in which it really changes its meaning.

What an absolutely astounding free-write! This is much that I can say. Mishu all here.
