In my case, I experienced vibrations and buzzing sounds in the following situations:
Astral Projection: When attempting astral projection, I would become unconscious and then realize I was awake, feeling vibrations throughout my body. These vibrations disappeared once I lifted my body out of itself. However, the experience was not extraordinary, appearing blurry and black-and-white like a dream.
Hyperventilation: Using breathing techniques such as holotropic or Wim Hoff breathing for extended periods, often more than a few dozen minutes, resulted in hearing a buzzing sound and feeling strong vibrations. Despite doing this frequently for several hours at a time, nothing significant happened beyond the sound and vibrations. A slightly unusual effect was muscle paralysis, which made it difficult to move and dulled my senses.
Successful Meditation: Occasionally, during successful meditation, I heard vibrations and buzzing sounds. The intensity varied, sometimes faint like background noise and other times loud like an airplane taking off. Despite the sounds and vibrations, nothing special occurred beyond this.
Emotional Uplift: When emotionally uplifted, such as when reading spiritual books or engaging in activities I enjoy, I often felt joy, happiness, and pleasure. These strong emotions sometimes led to experiencing vibrations, but nothing extraordinary happened beyond that.
Purification: During moments of intense fear, terror, anxiety, mental confusion, anger, hatred, and sadness, I heard vibrations and buzzing sounds. These noises accompanied a deep meditation state within minutes, along with a sense of bodily expansion and deepened consciousness. However, these strong emotions persisted.
Affirmations: Repeating affirmations like "I love" almost all day for several days led to experiencing vibrations. During this time, I felt a strong pressure and physical fatigue, as if something external was pressing on me. This sensation disappeared when I stopped affirming.
When I first encountered these experiences, I was surprised and intrigued. However, as I grew accustomed to them, they lost their novelty. The buzzing sounds and vibrations were just that—sounds and vibrations—without any profound experiences attached. Initially, I was excited and anticipated something different, but over time, I became tired and bored.
Hello, friend... We are consciousness having a human experience. Everything in this world is an elaborately simulated virtual reality. In order to experience infinite consciousness as if we were human, we must limit our consciousness. The human nervous system performs this role. It exists not to process information, but to limit the scope of conscious perception. So, you can either relax this nervous system by making it very tired, or you can temporarily suspend the restrictions on consciousness. For example, if you do very intensive meditation, your nervous system becomes overloaded and temporarily stops functioning, and in the process, you can temporarily feel a sense of unity with the universe. Or there are medications like ayahuasca. Alternatively, there is a machine in the laboratory that treats the brain with magnetic resonance, and when stimulated with gamma waves, it reports things like leaving the body or coming into contact with other beings. All of this requires the power of external tools, but there are also methods, such as holotropic breathing, that relax the nervous system by creating a temporary hypoxic state.
There are many ways to deal with fear.
Fear has certain limiting assumptions. Find those parts and fix them.
For example, imagine you are dreaming right now. Imagine being able to change the past, change the present, and change the attitudes and perspectives of others at will when unwanted situations arise. What if so? Of course, even if it is possible, you may feel fear, etc. But, what if you could actually do it and actually do it, even if you're afraid? Imagine this.
This is a way to change your mind into a state where you feel joy, pleasure, love, and freedom. If you switch to this state and you're feeling that way, even though you feel fear, it's not as strong and dominant as it was before. In this state, try focusing more on joy, freedom, and fun that are not related to fear. Then the fear will be forgotten as if it never existed in the first place, and you will only notice later that the fear is gone.
This can be done by doing or imagining something that you enjoy and like.
Try using ho'oponopono or the Sedona method (release technique). However, in my experience this is a very long and slow method. It takes a long time. Of course, it is quick and effective once you master it, but it seems to be an inconvenient and tedious task that takes at least several months.
Try to induce hyperventilation through Wimhoff breathing techniques or holotropic breathing techniques. When this condition occurs, senses and reason become paralyzed. At the same time, various thoughts disappear.
There is no need for any special training, just inhale and exhale quickly for a few minutes or more.
Focus on your inner background, inner silence, or the gap between your thoughts. At first, you may feel random thoughts, but if you keep paying attention to them and pay attention, at some point you will feel peace, joy, etc. It's like focusing more on the sound you want amidst noise.
However, in my experience, this method takes a long time to master. It appears that it will take at least several months to strengthen this feeling of peace to the point where it overwhelms fears and other factors.
Unlike the fourth hyperventilation, this is simply breathing deeply and comfortably. I have discovered that anxiety or fear is not actually caused by any belief or situation, but simply by habitually being tense and breathing shallowly. Of course, your nervousness or shallow breathing may have started with anxious or fearful thoughts. However, that is not a direct cause, but just a secondary cause.
Once you begin to practice this breathing comfortably, deeply, and consciously for more than a few minutes, you will discover that the thoughts that made you feel anxious or fearful are in fact irrelevant. At least it's not as intense as before.
I recommend the sixth method of breathing comfortably and the second method of pleasant imagination. Then, naturally, the first belief correction also occurs.
