Should I Continue This?

Today, when I was walking to school, it was so weird! Everything looked see-through, but not. It was like a holographic world. So, when I got to school, I went to my first period class (I was late), ready to be scolded. Instead, it was as if my teacher didn't notice me. And, I couldn't hear any real, complete words. She was just speaking gibberish. I went over and asked to sit in the front because I couldn't hear her. No response. I figured I was dreaming, so I slapped her (something I had secretly wanted to do for a long time), but my hand went right through her intangible face. Maybe everything  WAS just a hologram. But, my hypothesis was proved wrong when she collapsed to the floor, writhing in pain. Horrified, I ran, sprinting the whole way home. Surprisingly, I didn't run out of breath, and my legs weren't sore. And, I ran through everything I encountered. Buildings, cars,trees, everything, The only question now was, what is happening?
