Below is an excerpt from my eBook, The Medium’s Toolkit.
The ability to hear Spirits is called clairaudience.
Most mediums communicate with Spirits by talking to them. You can talk to a Spirit inside your mind and they will reply, inside your mind. This is called mental mediumship.
Until the early 1900s, when charlatans, posing as mediums, were trying to discredit actual mediums, mediumship was primarily made up of physical mediumship – bangs, knocking noises, light shows – and it was very entertaining.
To combat this and continue to prove life after death, mediums switched to asking for verbal evidence instead, and translating Spirit’s verbal messages has been the primary form of mediumship ever since.
While hearing Spirits externally is part of physical mediumship, today, it is more common for a Spirit to communicate with you telepathically.
When you get close enough to the energy field of a Spirit, it is possible to transfer thoughts between you and them. This is true whether you’re connecting with a Deceased Loved One, Spirit Guide or Angel.
If a Spirit comes close enough into your energetic space, they can transmit their thoughts, through words and messages that arrive spontaneously in your mind.
