A Story My Father Told Me

Apparently, when I had a fever as a child, I suddenly woke up and asked my mom, 'Why was Dad peeking in earlier?' But at that time, my dad was taking a bath (he usually takes long baths)... I don't remember it at all. Could it have been a hallucination, a dream, the work of a spirit, or just something my dad made up? If it was a spirit, could it have been my great-grandmother? Because I remember her being kind to me.
