Two encompassing themes to this collection: primarily, the evil of solitude, or how solitude equates with or drives one to madness; then boundaries, blurring and pushing them (of reality, knowledge, perception, life and death, even geography)
Celephaïs: Gorgeous in spite of the cold reality. From Kuranes dreams to mine... yeah, that's not disturbing at all.
From Beyond: The type of story one expects when one hears "Lovecraft". And it's freaking good.
Hypnos: *blink* Erh... OK. Like this wasn't disturbing, a final twist. I would have said it bore serious homo-erotic tones, but then... Begs for a second read. Or a tenth.
The Temple: That's what I call a bit of Karma for a stubborn nationalist.
Note: for some reason (and what I mean is lazy translation), it's titled as Santuario (sanctuary) in my Spanish copy instead of the closer Templo.
The Tree: Did not take the expected turn. And sent me on a wiki-walk that ended landing me on the seven wonders. Pretty imagery.
Actually, the whole collection, for all the horror elements, is powerful on beautiful and vivid imagery. The kind that plays as a magic-movie on your mind, fills you with wonder as you read and stays with you.
