The World Beyond Our Senses
Our five senses act as a filter, allowing us to navigate the physical world while hiding its underlying mechanics. Just beyond the narrow bands of light and sound we can perceive exists a vibrant, thrumming spectrum of sound energy. This hidden landscape of vibration is not just a scientific curiosity; it is the very medium through which the physical and metaphysical worlds communicate. From the deep hum of the Earth to the sharp clicks of a dolphin's sonar, and from the crackle of a distant radio station to the silent imagery that flashes in the mind's eye, we are immersed in an ocean of invisible communication. This blog explores the physics and metaphysics of infrasound, ultrasound, and radio waves, revealing their role as gateways and conduits for interdimensional interaction.
Infrasound - The Subsonic Gateway
The Physics: Earth's Powerful, Silent Pulse
Infrasound refers to acoustic waves with frequencies below 20 Hz, the generally accepted threshold of human hearing. These are not gentle ripples but massive, powerful waves with wavelengths that can stretch for miles. Generated by colossal natural forces—the grinding of tectonic plates in earthquakes, the eruption of volcanoes, the pounding of ocean surf, and the rumble of thunderstorms—infrasound travels immense distances with minimal energy loss. It is the planet's background hum, a subsonic signature of its dynamic activity.

The Metaphysics: The Resonant Door to the Unseen
Metaphysically, infrasound's physical properties translate into a profound spiritual function: it is considered a fundamental carrier wave for consciousness and a gateway between dimensions. Its ability to permeate solid matter mirrors its purported ability to "vibrate" the veil separating our physical reality from the astral or subtle planes.
This slow, pervasive resonance is thought to be the ideal frequency for the movement and communication of non-physical entities. Spirits, jinn, and elemental energies may use this subsonic band as a highway, much like a ship uses ocean currents. The unsettling feelings of dread, awe, or an unseen presence often reported in spiritually active locations frequently correlate with measurable infrasound. It does not carry a complex language, but rather acts as a foundational tone—a resonant door that, once opened, allows other forms of consciousness to perceive and interact with our world.
Ultrasound - The Sonic Image
The Physics: Seeing with Sound
At the opposite end of the audible spectrum lies ultrasound, comprising frequencies above 20,000 Hz. These waves have short wavelengths and are highly directional, allowing them to be focused into a precise beam. In nature, dolphins and bats are the masters of this domain. Through a process called echolocation, they emit rapid, high-frequency clicks and interpret the returning echoes. Their brains process this data to construct a detailed, three-dimensional "sound image" of their surroundings, effectively allowing them to see with sound.

The Metaphysics: The Telepathy of Imagery
If infrasound opens the door, ultrasound paints the picture that comes through it. The metaphysical proposition is that consciousness itself can utilize ultrasonic frequencies—understood as a qualitative energy, not just a physical wave—to encode and transmit complex visual information directly to the mind.
This concept provides a potential mechanism for phenomena like spiritual visions or spontaneous clairvoyant images. The vivid, often intrusive, imagery that appears in the mind's eye of a sensitive individual could be a form of psychic ultrasound—a data-rich packet of information that the brain's visual cortex decodes as a picture. This is not "hearing" a sound, but "receiving" an image transmitted on a high-frequency carrier wave of consciousness. It represents the development of the "inner eye," or the mind's ability to tune its receiver to these sophisticated information streams.
AM and FM - The Metaphysics of Radio Waves
The Physics: Terrestrial Signal Propagation
Our technological use of radio waves provides a perfect metaphor for interdimensional communication. The two primary modulation schemes, AM and FM, have distinct physical properties:
AM (Amplitude Modulation): Information is encoded in the varying amplitude (strength) of the wave. AM signals are famous for their long-range capability, especially at night, as they can bounce off the ionosphere to travel across continents.
FM (Frequency Modulation): Information is encoded in the varying frequency of the wave. FM signals are "line-of-sight," offering superior fidelity and clarity over shorter distances but are unable to travel as far as AM.

The Metaphysics: The Cosmic Broadcast
AM: The Long-Distance Spirit Band - AM's physical behavior mirrors its metaphysical function. Its use of the ionosphere as a resonant relay chamber is analogous to broadcasting from the higher astral or mental planes down to the physical. The ionosphere may act as a literal and energetic capacitor, recording and transmitting impressions from other dimensions.
This explains why phenomena like Electronic Voice Phenomena (EVP)—where disembodied voices appear on recording devices—often manifest in the lower-fidelity, noisy characteristics of AM. The fragmented whispers and messages buried in static sound precisely like a signal struggling to reach us from a great distance, relayed through the "cosmic static" of the ionosphere.
FM: The Clear Channel of Focused Consciousness - In contrast, FM's metaphysics are about clarity and precision over breadth. Its sharp, high-fidelity, but localized signal represents focused, high-intention communication. This is the domain of clear-channel telepathy, the direct transmission of complex ideas between two connected minds, or the sharp, unambiguous commands used in high-level magick and manifestation. It is the "laser" to AM's "floodlight."
Conclusion: Tuning the Human Receiver
The universe is a symphony of vibrations, and what we call reality is merely the channel we are tuned to. From the subsonic gateway of infrasound to the image-carrying waves of ultrasound, and from the long-distance broadcasts of AM to the sharp signals of FM, we are constantly bathed in a sea of information and influence.
The key to navigating this hidden spectrum lies not in building a better external device, but in refining our own internal instrument: our consciousness. By understanding these principles, we can begin the conscious work of tuning our awareness, learning to listen not just with our ears, but with our entire being, and ultimately, choosing which frequencies we allow to shape our reality.
