Recently I have been quite interested in Astral Projection and found this method on the internet:

This method requires no concentration or deep relaxation procedures, but unlike all the others, it will need the assistance of a second person.
Warning: This method can be dangerous to those with a weak heart, so consider this wisely!
Whoever you choose to assist with this technique must have a certain degree of patience as they will have to watch you from the point of settling down to the point of almost falling asleep.
The method is quite simple. All you will be required to do is lie down on your back and hold one forearm up in the air so that your elbow is resting on the bed, then remain in this position as you attempt to drift off to sleep. Your assistant, who should be sitting quietly nearby, is required to watch your arm as you start to fall asleep and notice how it starts to sway as you lose consciousness.
As soon as your arm has fallen onto the bed, that person will then have to shout out in your ear, "GET OUT!" or "JUMP OUT!"
The idea of this is to make you jump out of your skin, literally. If you have any other people in the house at the time, i.e., family members, it's usually a good idea to tell them about the experiment before you start!

Does anyone think this would actually work?

Also I was just wondering about when you project, say if you went outside, would you see everything actually happening at that time like cars going past and people walking?
