I heard some people can leave their body and travel any where they want. Is there fact behind this.

This is extremely true and real. In order to succed in such a venture one must first follow these simple step.
materials you will need are , a clothespin, a straw, duct tape. Purple trianlge painted on the ground at the edge of a cliff.

First you will need to place a strup of duct tape over your eyes. This will insure that there are no interruptions.

Place the clothespin onto your nose. Remember, the only senses that should be available to you are sound.
Next sit cross legged in thele trangle at the edge of any cliff in your area. This will help you to better understand and connect with nature. Then place the straw into your mouth and take deep breaths through it. You will eventually begin to feel a strange dizziness come over you.
Now stand up , turn around 3 times and walk forward. You should then start to experience a falling sensation.
Congratulations ! You are now leaving your body !

I have read accounts of people being able to do this, apparently even under scientific conditions. One guy was supposedly locked in a room under supervision to ensure that he did not leave his bed (which was bolted to the floor). A card with a random 4 digit number was placed on a shelf which was positioned at such a height and in such a place that there is no way he could have reached it. When he woke this guy was able to tell the observers what the 4 digit number was.
