Here’s an excellent visualization method to try when you want to Astral Project during the night. There’s nothing complicated about it and you might find it’s a really pleasant way to drift into sleep. Give it a try and let us know how it worked for you.
The key for astral projection success with this Visualization Method is to focus and maintain your complete attention away from your physical body as you drift to sleep. One of the easiest ways to do this is to put your attention upon a person, place, or object located some distance from you. This can be a loved one from which you are separated, your favorite vacation spot, or a gift that holds some special meaning for you.
Whatever you select should be an actual physical object you know, not an imaginary place or person. Select an object or place that is easy to visualize and holds the most interest for you. Become completely absorbed in it. If you like, role-play some kind of interaction to keep your mind focused.
Continue your visualization for as long as possible as you allow your physical body to completely relax and fall to sleep. It’s important to maintain a detailed picture of the object or place and your interaction as you go to sleep. As you doze off, attempt to boost your emotional and visual connection as much as possible. This method is excellent bedtime visualization.
Keep in mind, the more emotionally involved and focused you are, the more effective this technique is. Have fun with it and maintain your visualization as your last conscious thought as you drift off.
