Coming back to this now because I thought Facky saying Alice in Wonderland Syndrome was a joke, but that is actually a term for this experience:

Alice in Wonderland Syndrome (AIWS), also known as Todd's Syndrome or Dysmetropsia, is a neurological disorder that distorts perception. People with this syndrome may experience distortions in their visual perception of objects, such as appearing smaller (micropsia) or larger (macropsia), or appearing to be closer (pelopsia) or farther (teleopsia) than they are. Distortion may also occur for senses other than vision.[3]
