A book you can crawl into

I'm not sure how to describe it, but I'm looking for a book that makes you feel like you're almost lingering in an alternate dimension. The closest to what I'm looking for is Piranesi by Susanna Clarke. I loved the quiet, mysterious and otherworldly feel of the House. I guess what I've been searching for ever since finishing that book is a liminal space you can sort of crawl into and make a home out of in your mind. Anything fantastical, weird and strangely comforting. Bonus point if the main characters is mostly traversing the place by themself. Open to any genre. TIA!
