You have a room where time is slower, if you look through a window, will everything inside look faster?

Well, here's what I know about the physics of this, and I don't know technical terms so bear with my layman explanation:

The more you move through space, the less you move through time. So if you are moving at the speed of light, you are less affected by time than everything around you. You moving at light speed will appear to be moving in slow motion to an outside observer. Not only would you appear to be moving in slow motion, but you would also appear to be contracted (if you were in a car, the car would look shorter to outside observers). However, to you inside the car, the inside of the car would be normal, but everything outside would look warped and like it's rushing by, kind of like warp speed in Star Wars with the stars warping and looking like lines going by them.

Here's a hypothetical scenario (I made up the numbers to get my point across, I'm unsure of the actual math): Now, let's say you at light speed go from point A to point B. It took you 5 seconds at light speed. You are 5 seconds older at point B than you were at point A because it took you 5 seconds to get there, therefore 5 seconds have passed for you. However, an outside observer would see you going in slow motion and they would see you take 5 years to go from point A to point B. The outside observer, along with everything else outside the car, experienced 5 years passing... that observer is 5 years older, so is everything else. However you only experienced 5 seconds of time. Essentially you travelled 5 years into the future in only 5 seconds.
