If I were to imagine myself to be an eagle, would that mean I could fly? If I couldn't in reallity fly, would that mean I'm really not an eagle?

By today's 'enlightened' thinking, no, it would not mean I wasn't an eagle. It would me that my true eagle self has a disabiliy. I would then be entitled to a disability check and species reassignment surgery....at your expense.

No, but given this precedent it would mean that everybody else would be forced to pretend that you could.
