I ended up spamming the psychokinetic shove earlier and a coffin ended up pushed to the side. I went to disarm traps and found myself not moving with my keyboard. Afterwards I ended up thinking I had a keyboard glitch at first since I ended up not moving when I tried certain directions. I later realized that it was a wall. Crystal healing marked areas are the ones I cannot walk over. Spamming psychokinetic shove cannot dislodge the crystals from the invisible wall.
