That's tempting, but you can't just get out of evidence by appreciating the other person's perspective. The alleged abductee is in a special position to evaluate whether or not she is joking or lying with a confidence others cannot share. But the weight of the evidence still suggests a psychotic episode or hallucination and the alleged abductee does not have privileged evidence regarding that proposition (she might have some reasons to doubt it but not enough to counter the fact that it is the dominant explanation).
