I think I may have experienced this, but it could be related to my schizoaffective disorder. I used to go to museums a lot when I was younger, and I felt like I could get lost in the paintings (especially landscapes and portraits), sometimes physically wandering through them in my head. Like a really intense daydream. Or if I saw a really amazing work of art, I would be filled with awe, more at the overall work and how the details work together than the details themselves... Both experiences were very disorienting. This happens even more when it comes to natural beauty; I feel very disoriented and detached from others. I feel I am seeing something they cannot. Often I lose touch with my body and feel disembodied (both with art and nature). I sometimes get tunnel vision. Beyond that it starts to get delusional (a beam of sunlight being a message, feeling the environment is trying to communicate with me, eventually I may start hallucinating voices and people) but at a low level it can be a pretty pleasant experience. It's pretty much exactly how I imagine being high would feel.
