I had a large file to copy from my laptop to a friend. We were on a break between lectures - no external drive, wifi way too slow - so we used cable. The copy was taking a while so eventually we started making jokes about data flowing down the cable faster because of, you know, gravity. It didn't take long before we placed the receiving machine on the floor and... the speed increased. Not radically, but definitely more than what you'd expect from random fluctuations. We replicated the experiment three or four times, in both directions. Every time when the receiving machine was physically below the source the transfer was better. To this day I can't explain it and to me this is a proof of how a relatively simple and well understood system can be unpredictable.
Both these computers were using hard drives, as in, rotating magnetic disks?

This is a kind of "X files" thread.
Post experiences which spooked you, which made you doubt reality, mathematical or physical laws, your sanity, memory or perception. The more improbable the better, but no second-hand legends please, share only what you personally experienced. If you had the event later explained rationally please use rot13 to avoid spoilers.
