Footsteps and other anomalous sounds such as Knocks and Taps rally skeptics who call into question the physics of such phenomena and blame matrixing as the common culprit. Defenders of footsteps as a well and true paranormal phenomenon conjecture that it is an imprint of a residual haunting, or even that it is an indication of parallel dimensions.
