I had a dream that i time traveled to the past and ended up in a lab with abraham lincoln and albert einstein working in it. and we did something to piss them off and so we had to quickly leave and so we started driving (how we time traveled) they figured it out (einstein and lincoln) and chased us in a t-model ford through time. and in my dream to break the speed of light was only 360 mph and that was how you time traveled. so by my dream logic you time travel when you fly.
also einstein and lincoln worked in a lab together and were friends.
