[X-Men] Is it possible to live your whole life without knowing you're a powerful mutant? Are/were there any?

I know when Charles uses the Cerebro he can see all the mutants in the world, but is it possible you're an Omega level mutant but...you just don't know it? Maybe you have a power in a very specific criteria and you lived your whole life never knowing that?

Are there any mutants like that in X-men?

Omega level mutants have fine control over a fundamental force of nature.  It's possible someone like that wouldn't realize it, but it's very unlikely.

The thing about mutant powers is that their use is reflexive unless specially trained.  Think of it like breathing or blinking.  If you focus on it you can definitely control your breathing rate or blinking (to a reasonable extent) but if you don't actively spend time thinking about it and learning to handle those muscles, you won't have much control.

In an Omega level mutant that reflex isn't breathing quickly, it's tearing apart the fabric of reality.  That tends to be a lot more noticeable than mutants who reflexively make basil plants grow quickly, so Omega level mutants tend to know something funky is going on.  The broader and more impactful your power, the easier to realize what's up.
