A teleportation hallucination?!

Jessica continued breathing in and out, in and out, her eyes still closed. After hitting that joint she felt almost sleepy. She tried to focus on her breathing to stay awake, but it had the opposite effect. She could still faintly hear the witch humming, although it was gradually becoming a bit distorted. She could still smell the incense and the yarrow oil.. but those were becoming distorted, too. Jessica tried sleepily to lift her heavy eyes. All she could see were colors. Nothing solid, she was in some kind of abstract and formless space with nothing but splotches of color as far as Jessica could see.

Its hazy - where is she? Is this a dream? Is this still the witch's house?

Jessica is starting to recognize certain objects coming into clarity.

As the shapes around her became more defined, Jessica could see where she was - and she wasn't in the witch's house anymore - she was in public - still completely naked! How was this even possible? Where did the witch go? Oh god, this is insane! This is a nightmare!
