An 80-year-old man sleeps in my bed.

You said you didn't, you weren't married, and your bed was slept by an 80-year-old man and belonged to someone else. Nothing is clear only about these things. If you believe that superstition, it will become more and more profound and annoying. But if you don't believe me, everything will be fine. What's wrong with people in their 80s and 90s? You are a task in bed, maybe in the future. Don't think too much about everything. If you think too much, you will feel very tired. Don't think too much about everything. Too many, you will feel that everything just goes with the flow, everything just goes with the flow.
