Definitely not a dying declaration. Declarant has to have genuine expectation of imminent death.
Not an excited utterance since it wasn’t made at the moment of experiencing the creaks.
Not a declaration of then-existing mental, emotional, or [physical condition. (That she was feeling uneasy would be, but as to what she allegedly heard, it would not.)
Not a present sense impression because it was not made in concert with an act or conduct.
ALL of which is just my opinion.
Counsel is correct, but is there anyone who knows how to pronounce gestae?
