A non-existent force of nature omitted by comfortable mattresses, making you unable to get out of the bed.
"Aw man, it's 6:30. Better get up for work. Oh no! The accursed bed magnet has been activated!"
*falls back asleep*
An occurrence where in you can't get off your bed and get on your feet after a long sleep. Your brain tells you have to wake up but your body is not responding.
I missed the bus, I was stuck on my magnet bed the entire morning.
