The astral plane is a real place that can easily be experienced by us. Lucid dreaming, OBEs, and astral projection are all doorways into the astral plane which is an entirely different dimension of the unvierse. But just like any plane of existence, there are entities that that inhabit the astral plane who want nothing more than to trick you, scare you, manipulate you and mess with you psychologically.
During an extremely vivid lucid dream experience I had, I found myself hovering over my neighbour hood. In front of me appeared a being with red skin wearing a red cloak with black markings on his face. He smiled at me in a way that almost said “I got you now”, and then a third eye appeared on his forehead. He opened it at me, and when it opened it I got sucked into it and experienced a moment of disorientation followed by a few seconds of complete darkness.
When I opened my eyes, I found myself hovering over top of my body 3 feet in the air in my bedroom and was terrified. I frantically tried to wake myself up into waking life and began to panic. This was my first out-of-body experience, and it happened as a result of being unprotected and messed with by an entity who took pleasure in taking advantage of my ignorance. If you are in the astral plane and don’t know how to navigate it or protect yourself, you can wind up in the hands of a negative astral entity who wants nothing more than to mess with your mind and scar you psychologically.
They can’t kill you or harm you physically, but if you are not protecting yourself then can leave a permanent impact in your mind and energy field. Here are some very useful ways to help protect yourself against negative astral entities:
1) Pray

The astral plane is not the only spiritual plane. There are many other higher glory realms populated by beings of light that want nothing more to reach out to you. Even Jesus, the King of the glory realms, is willing to help you defend yourself against dark spirits, but no positive entity may impose themselves on you against your will. Their goodness and fairness prevents them from violating your free will. When you pray, surrender, and reach out from your own free will, you will always be heard and protected.
2) Control your thoughts

Remember that spirits of darkness feed off of the energy of fear. Practice meditation in your waking life to learn how to develop a new relationship to your mind and experience yourself as something beyond your thought stream. Learn how to ground yourself in the present moment and silence your mind. Your understanding of your mind in waking life will translate into your experience of other dimensions. You can then choose not to give in to thoughts of fear and paranoia, and you will no longer be an energetic magnet to beings that feed off of your fear.
3) Raise your vibration in the astral plane

Perfect love casts out fear (and negative astral entities). Here are some things you can do to raise your vibration while you are in the astral plane:
Have a sense of humour about your experience. Be lighthearted and don’t take things too seriously. You’re only dreaming.Cultivate love within yourself by understanding your experience is all part of a dance of energy.Close your eyes and think back to a time you experienced love. Stay there.In your mind, create a protective shield of white loving light around yourself.Worship God. Sing worship songs.
Think of having a high vibration as a form of preventative medicine against negative astral entities. It’s much harder to protect yourself against something when it is already in your presence. It’s kind of like trying to fight off a cold when you already have a sinus infection versus fighting it off with proper sleep and diet prior to it reaching that point in the first place.
Remember that no demon or negative astral entity can torment you if you are protecting yourself. If you are cultivating love within yourself, praying for protecting from your heart, and create energetic shifts within yourself to raise your vibration, you are going to be vibrationally incompatible with negative entities who want to scare you and manipulate you.
