I met a "Lord of the Cottege" entity in my dream, would appreciate insights into its meaning

I was a child and we (my family and I) went to a cottage by a large lake surrounded by a forest. It was dark and ominous. At first everything was normal, I was even doing some homeschooling I think. I spoke to the next occupants of the cottage, but everything went wrong.

There were "ghosts" and creatures trying to get to me. They were all invisible and only I could notice them. There was a "king" after me and I had to defeat him to escape the cottage. I saw a mirror, well actually 2 mirrors but only I could see the second mirror. I walked through the mirror.

I suddenly saw the ghosts, they had pyshical forms now. But there was a...being. no gender or face. I got the feeling this was "the sun" or it had a "sun aura". Like a being of complete light. It was like the "lord of the cottege", a very important but detached figure. It was very nice. I got an other worldy feeling from this place. It looked like a regular cottage with large windows and sunlight streaming through. But I "knew" it wasn't a regular cottage and i was actually in some kind of alternative dimension or something. A place that people like me weren't supposed to be in. But it wasn't threatening, it was very welcoming. While the cottefe was dark and had an ominousfeeling, this alternate dimension cottege felt warm and inviting. Thr sunlight was so warm and comforting too. A monster tried to attack it, or the "Lord", but nothing happened and it didn't even react. I remember sitting at a table with it, but there was no food, water or bathrooms. Somehow that was my clue that we were in a different dimension. I felt safe with this entity. It explained to me that I had to defeat this evil "king" and that these monsters belonged to this "evil king".

I then walked back through the mirror and back to my family. It's tough to remember the rest. At one point we tried to use a boat to cross the lake, but the demon king grabbed me and pulled me under the lake. Sorry some parts are so fuzzy. It was a very strange dream.

I'm especially curious about this odd "Lord of the Cottage" lol. That's literally the title that popped into my head when I met it. It's strange how vividly I remember sitting at the table with it, everything felt so warm and welcoming. I don't remember it's face, but it didn't feel human. Usually non-human things in dreams give me anxiety so it's really strange how this one felt so welcoming and friendly. Anyway, just thought I'd get some other opinions on it. Not sure if it's relevant but I'm not particularly spiritual or religious, I guess that's why this dream has stuck out to me. It feels very spiritual despite my lack of belief.
