Demons can smell like sulfur, roses, cologne...anything! They can also appear as: an angel of light, a dead person or child, a spirit guide, a healing spirit (reiki), an alien, a fairy, a dwarf, a spirit animal etc! We can't safely discern them!

The recommendation is therefore that the stimulation should be applied with a 2500Hz carrier medium frequency sinusoidal alternating current, burst at 50 Hz (10ms ON: 10ms OFF) at a maximum tolerable level.
Which type of noise has sound at every frequency within the range of human hearing? Is a high frequency sound heard at a high pitch a high wavelength or a high speed? When you generate a high frequency sound, through earphones or a speaker, you hear it as a high pitched sound. Higher frequency ==> higher pitch. Higher-frequency sounds hâ¦ave shorter wavelengths, and sounds of all frequencies have the same speed, as long as they're all moving through the same stuff.
