Yes. For example, IV Ketamine can yield not only immediate relief in a chemical sense, the treatment itself results in a fully-aware, balls-tripping, metaphor and symbolism-filled, time and space-warping experience in an entirely fictional space. With thoughtful guidance prior-to and after each experience, a series of them can, for example repeat a message until you "get it," or each may deliver a component of a profoundly larger message when they are combined, weeks later. What you do with it all will determine what you get from it.
