Something makes Buffy see the 'true' form of things & she sees Spike as William

After season 4, so Riley and Buffy are together and I think the Initiative is gone.

Something happens to Buffy to make her see the true forms of things. She first notices when she wakes up and sees a glass of water as disgusting, green-tinged and with things floating in it. Then she goes downstairs and sees her Mom looking sick and with leeches on her and freaks out. Anya looks like Aud, a very sweet girl with a light around her. Willow is black-haired, black-eyed and veiny. Tara glows. Riley looks like a bloated corpse. Spike is very complicated- Buffy sees him as William, and a glow around his heart that has words stream out of, writing poetry across his chest before the lines vanish. There is a rippling curtain of darkness behind him that seems to whisper to him.

I can't remember anything about the plot, just these details of what Buffy sees in people. Can anyone help?

I think I remember this... Buffy hangs out with Spike in the cavern under his crypt. And after this spell is broken, Riley and the Scoobs are worried about Buffy and Spike growing closer, right? Can't remember where i read it, sorry.

Finally found it! XD
