Other people no longer appear in my dreams

I’m terminally ill and generally don’t go outside my house, except to get deliveries from my porch. The only times I have seen anyone irl in the last 2+ years is when I went to the hospital on Christmas and, two months earlier, when a delivery driver returned to give me an item they had forgotten to leave. In the ~year before that, a neighbor yelled hello from across the street.

Somewhere along the way, people disappeared from my dreams, without me even noticing, until it dawned on me this morning. While dreaming, I am out in the world, having adventures completely alone. I do interact with people, but only by text and a rare call , just like irl.

The funny thing to me is that my dad became paraplegic late in life and once told me, out of nowhere, that he’s never in a wheelchair in his dreams, but my experience is the exact opposite.

Please don’t feel sorry for me. I’m still having interesting dreams that can be really fun. I’m not lamenting it. I just find it strange.

Edit: my illness is degenerative and no treatment is available. Medication became ineffective. So, I no longer need to go to the doctor. They prefer I do go every three months, but it became just a check-in to monitor my decline, which didn’t help me in any way and depleted my limited energy with no benefit to me

Edit 2: Someone comment that I don’t remember my dreams, implying that people do appear. While I understand this thought, I do remember many of my dreams after waking. As I first start to wake, I always have a few moments when I remember what my dream was about, although not the entire plot. If I consciously make an effort, I can maintain this plot memory and think it over when fully awake. It’s been that way all my life. People used to be part of these memories, but they’re not anymore, except to communicate with remotely.

Please don’t feel the need to poke holes in what I’m experiencing. I have a much better understanding of it than those who haven’t experienced it. Ask as many questions as you would like to, but totally dismissing it with no knowledge of my situation is completely unacceptable.
