Not everyone believes in ghosts, but for those who are haunted, they can be truly terrifying. This article will provide you with signs to determine if your house is haunted, how to eliminate common (non-supernatural) causes of 'ghostly' phenomena, and ways to banish ghosts if your home is truly haunted.
Steps
Eliminate Natural (Non-Supernatural) Possibilities

Ensure the haunting isn't caused by infrasound. Low-frequency sounds can cause nausea, fear, and even create shadows in corners. These phenomena are caused by infrasound vibrations, which depend on the intensity of the sound waves. French robotics researcher Vladimir Gavreau is said to have used infrasound to create these effects on himself and his colleagues.
- Animals can sense infrasound that humans cannot hear. Scientists believe that this ability helps animals predict natural disasters.
- Create a low-frequency microwave. You will need to buy an antenna, but this device can be found at most electronics stores and is quite affordable. Once you have the microphone, find a glass jar with a 6 cm diameter. Stretch a 30 cm balloon around the mouth of the jar. Cut off the air-blowing end of the balloon and secure the remaining portion tightly to the jar, ensuring it doesn't wrinkle. Attach a NdFeBco magnet with a diameter of 1.5 cm to 2.5 cm and a magnetic force of 5000 gauss or more. You'll also need an oscilloscope to convert electronic signals into waveform graphs. These devices are slightly more expensive, but they can be bought for about $45 on eBay.
- Alternatively, you can contact the Physics department at a local university to inquire about suggestions for setting up a low-frequency microwave.

Eliminate non-supernatural factors. Check around your home. Is there a landfill nearby? Sometimes, methane gas rising from the ground can emit a sulfur smell and ignite.
- Occasionally, the "ghosts" you see are simply strange reflections of light from a flat surface. Human vision and other senses can easily be misled, so what you see may seem too unbelievable to be real unless you investigate thoroughly.

Get a mental health check-up. Often, those who claim to see "ghosts" may have mental health issues. Before engaging in any unusual actions in your home, seek professional help. This doesn’t mean your house isn't haunted, but rather to rule out external possibilities.
- Similarly, you might want to ask someone else to verify your experiences. If you are the only one seeing or feeling something, it may be time to visit a psychiatrist. However, if others share similar experiences, you should first explore natural causes.
Assessing the haunting phenomenon

Record your experiences. Once you've ruled out natural causes, you'll need to document your haunting experiences to understand better how to deal with it.
- Use a recorder to try communicating with the spirit. Record some questions and wait to see if the spirit responds. Responses may not always be verbal, but you might receive a signal that will guide you in eliminating the entity. Ask simple questions, typically requiring a yes or no answer. The easiest way to communicate with a spirit is to ask questions and request a knock as a "yes" answer and two knocks as "no".
- Take pictures of areas where you suspect paranormal activity to see if anything appears in the final images. Use a flash when in a dark room, otherwise, the camera will only capture darkness. However, it’s best to rely on natural light so the camera flash doesn’t create confusion. Keep in mind that ghostly images often appear as orbs, while other phenomena are usually just dust on the lens or refracted light from airborne particles.

Ask others to verify your findings. Inquire whether your family members or roommates have felt or seen the same things you have. Have they heard footsteps, door knocks, or other unusual signs? Try not to influence their experiences with your own findings.
- If possible, consult a reputable exorcist or psychic and share your discoveries to hear their opinion. If you have the funds, you could invite them to visit your home and see if they detect anything that you might have missed.

Don't be disheartened if your haunting turns out to be nothing mysterious. As any reputable exorcist would tell you, most ghostly images can be explained naturally. This does not mean that spirits don't exist, though!
Politely suggest that the spirit leave

Be confident when dealing with a ghost in your home. Like animals, ghosts are believed to react and are nurtured by fear. There are very few (if any) cases of humans being harmed by spirits, so what you're dealing with is likely only discomfort and perhaps a sense of unease.
- When speaking to a ghost, use a firm tone as if talking to a misbehaving animal. Be strict, but not malicious. The ghost may be the lingering soul of someone else. Their death may already be a tragedy for the spirit.

Perform an exorcism. Especially for Catholics, an exorcism is meant to drive away Satan and his followers. However, this method may not work for you if you're not Catholic. Look within your own religion, as all religions have ways of dealing with various types of spirits. If you're Catholic, don't attempt the exorcism yourself. It's better to consult your local church for suggestions.
- In Hinduism, reading chapters 3, 7, and 9 of the Bhagavad Gita (Bhagavad Gita) and sending it to the spirit will help release the souls from captivity. Similarly, chanting mantras, keeping holy images, or lighting incense during Puja rituals may help liberate trapped spirits.
- Jewish rituals help heal both the possessed person and the haunting spirit. These rituals must be performed by a Jewish rabbi who is well-versed in Kabbalah mysticism.
- Many exorcism rituals exist across all cultures and religions, so you may find one that suits your needs. These rituals are based on different cultural views of spirits and the afterlife, and there is no single definitive doctrine on spirits.

Cleanse the house. After banishing the spirit, you need to cleanse your living space to ensure the spirit doesn't return and to prevent other souls or ghosts from entering. As mentioned, the methods for cleansing physical spaces are as varied as the religions of the world. Here are just a few of the most common methods.
- Burn sage or cedar. It's believed that this can drive away negative energy, and in many cultures, burning incense is also considered a way to purify the space.
- Ring bells in every corner of your home. It's believed this disrupts negative energy and encourages positive energy. It's important to do this more than once, as bad energy can come from many sources.
- Physically clean the house. This will create a fresh atmosphere and help prevent bad energy from returning.
Advice
- Very few ghosts (if any) are harmful. Usually, the best approach is to leave them be. Think of them as a strange guest (even if they sometimes cause inconvenience).
Warning
- Make sure that the "expert" you're consulting is truly an expert. Many fraudsters work within the spiritual realm.
