Let me start by saying everyone is different. I’ve always been one to see things - shadows, figures, animals that aren’t there, etc. I wasn’t really able to feel until I started working with energy more, and the energy awareness course really boosted what my own practice had started.
But with negative entities there was always this “knowing” feeling inside me. I knew it was there and I knew it didn’t intend on being helpful. I understand it to be very alarming and uncomfortable, especially if not prepared.
The thing about negative entities is they are usually there for energy. They gain energy from you. They feed off any little bit of negativity, and increase the feeling within you so they have more to eat. Sometimes they are brought into your home or your space without your knowledge if you let your guard down. If they get in you need to first rid your being and home of them.
If you have a servitor, I would suggest asking the servitor to rid your environment of negativity and negative beings.
If you do not have a servitor, you should use Negative Entity Removal or Exorcism or De-Inhabiter. One of these may work best for you, and I would use it 3 times or until you feel better. After you start to feel the entity is no longer there, I would listen to Love, Gratitude Appreciation a couple times, and possibly Internal Alchemical Crucible. Only after banishing the spirits with these audios should you start your protection audios.
Another thing that helps is envisioning your being enveloped by the most divine white light (usually a sphere or an egg around you). Enlarge this sphere of pure love light until it covers your home. Keep the intention of banishing negative entities while enlarging your sphere. Once the sphere is big enough, set the intention of it being active at this range around your being for 12 hours, protecting you from negative entities and negativity in general. Know and believe that your light will not allow negativity of any kind to enter.
You can do this first thing in the morning, and again right before bed. Or form your own schedule so you are consistently protected throughout the day and night.
I hope this helps you! I used to deal with negative entities quite a bit due to my own ignorance, but now I do not have any issues with them. They do not want to come near you if you are projecting love light. It’s the opposite of what they need for sustenance and survival.

There are quite a few posts about entity banishing on the forum.
