You are posting in the forums, why not search for this subject here? This site has been around for 10 years, I believe. I'm sure you can find at least one article on it.
If not, you have the entire internet at your fingertips. Perhaps you can do a little research on your own before asking others to do it for you, or explain it to you when you have all the knowledge right in front of you. All you have to do is search for it.
It is completely possible. Here's a simple thing I've used:
When you're home alone, go into your room and make sure it is dark and absolutely quiet. Lay down and start deep breathing to put yourself into a relaxed state.
Next, start thinking of memories. Start with a memory from a week ago, then to a month, three months, and so on. When you get to when you were born, keep pushing. For me, I felt a wall almost trying to keep me from going back further. Visualise pushing through the wall and going into your past life.
I know this helped me a lot in the past and I hope it helps you too. :)
