Not advocating one way or the other, but this is often the reason people give for enjoying the rare/occasional use of things like LSD or psilocybin. By temporarily attenuating the "default model" established in early adulthood - which allows our brains to operate more efficiently by setting much of sensory input and perception on autopilot - one might approach and consider the mundane with the proverbial "fresh set of eyes".

I don't mean to argue that this is an ideal way to achieve this effect, but it's definitely a major part of the appeal.
