Hi Aster. You have described typical characteristics of the presence of spirit beings. The kind of spirits you have are causing you ill feelings and to react negatively. Unless you are so fascinated with the occult that you are willing to spend literally decades studying it and learning how to interact with these, "unseen forces," then you need to get rid of them immediately. Fortunately, yours are very weak in power level. They're only making you feel as though you're being watched (the most common of all symptoms), evoking fear in you, and making noises. However, the more you allow your imagination to dwell on these unseen forces, the more form and detail you will give them---the more you will empower them---which is exactly what they want from you. Therefore, you've got to get rid of them before both you and they reach that point. Here are ways to get rid of them:
1) Play a mental game with yourself. Refuse to acknowledge that the spirits exist. In order for a spirit to exist, its existence must be acknowledged by at least one human being. Your spirits are working on you to try to get you to acknowledge their existence. Don't give them what they want. Refuse to acknowledge their existence. Concentrate intently on trying to come up with logical, rational, and scientific explanations for the so-called phenomena you are experiencing. Be confident in your reasonable explanations.
If that doesn't work, proceed with the following:
2) Inundate your surroundings with Holy Objects and invoke Holy spiritual beings. For example, if your religious background is Christian, then consider hanging crucifixes, Christian, or Celtic crosses in all of the rooms of your house. Consider wearing a cross around your neck. Frankincense was one of the gifts of the Magi to the Messiah. Try burning frankincense in your house. Any objects commonly considered Holy will do. Invoke the Christ in prayer. Ask him to protect you. Invoke angels, especially St. Michael the Archangel, in prayer and ask them to protect you. Consider playing Christian music.
I'm using Christian examples here because they are the most common in the U.S. However, whatever is considered Holy from any other religions will also work, as long as they conform to your beliefs. For instance, if I am a Christian, invoking an Egyptian god probably will not help me.
Spirits such as the ones you are experiencing are those who hang out on the Lower Astral (close to the Earth). They are often, "Discarnate Entities," (spirits of the dead). 20th-century Magician, Israel Regardie, referred to these Lower Astral beings as, "Astral Garbage." I am more respectful. I prefer the description: "residual human consciousness without a human body." Usually, discarnate entities continue clinging to the Earth because they are afraid of, "Facing the Divine," for whatever reasons. Some of them feel that they committed unpardonable sins when they were alive. Some of them feel as though they left some things, "undone," before they died and are trying to obtain closure before they face the Divine. There are lots of reasons. But, in all cases, discarnate entities fear facing the Divine and not being permitted into heaven. As such, they generally hate being around Holy Objects and Holy spiritual entities (gods, archangels, saviors, etc.), can easily drive them away.
One important thing: I learned this from two other authors on this forum, tviscante and MaskedFox. If you decide to go with number 2 above, make sure your, "Holy Regimens," are frequent, consistent and over an extended period of time. If you just do them as single shots here and there, you'll probably not get rid of your spirits for good. They'll probably return. So, you've got to keep the Holy Regimens going.
3) I'm reluctant to recommend this to you because it is an esoteric operation. The occult can be very addicting for some people and I'm not at all convinced that addiction, or obsession with anything is a healthy way to live life. However, it is very effective. It is called, "The Lesser Banishing Ritual of the Pentagram." It's purpose is to surround oneself with the four Archangels for protection. And, it really works. You can read more about it by clicking on the following link:
http://en.wikipedia.org/wiki/Lesser_Ban ... _PentagramThe article describes the ritual accurately. However, it doesn't describe how to actually perform the ritual. It's pretty common, though. You should be able to find it easily in the Magic sections of libraries and booksellers.
I hope I've helped you. Good Luck!
