Sounds a bit like my sister-in-law, who is otherwise a great lady and doing strong in her 70s (same decade as I'm in.) Some years ago she and my brother were staying at our parents' NNJ home, using the spare downstairs bedroom. About 4 AM one night she shook my brother awake, saying, "There's a spider in here! I can hear it!" My brother dutifully got up, turned on the light and proceeded to search all over the room for about 20 minutes, finally discovering a spider about the size of a pinhead. He dispatched it, carefully showed the carcass to his wife, and all slept peacefully the rest of the night.
