Looking for a book that questions reality

Looking for my next read to make me question what is real. Kind of like Satoshi Kon's movies (perfect blue, paprika, etc). I suspect I am in a major depressive episode and I've also been dissociating for the past week or so, so I'm already finding it hard to believe I'm "a real person" and not "made of wax." I think this state would enhance my reading experience.

Does not hurt if it's feminist as that's what I've been into recently. To give you an idea, my three recent reads are "the yellow wallpaper" (Perkins Gilman), "a doll's house" (Ibsen) and "the vegetarian" (Kang).
