Types of readings
There are 3 types of readings really
A psychic reading with very little or no evidence of spirit, which would be about you and your life. This could cover health, financial, family, work, personal, spiritual matters etc and would be guidance or giving you answers to questions you might have in your day to day life. This is connecting and reading your energy.
Mediumistic readings are solely evidence of loved ones, this could be their description, character, shared memories, evidence of their earlier life hobbies etc. This is connecting to spirit energy and also proof of them being around you, with guidance and maybe answers to questions relating to your life.
Card/tools whether angel cards, tarot cards, crystal balls or jewellry etc are primarily psychic and cards can be for a time frame. I read them intuitively but card readers learn the meanings of each card and which cards go together.
A mediumistic reading in my opinion, is a more balanced reading. In a psychic reading it could be what your wanting to hear but it's not to say it will happen or be best for you.
Past present and future would basically be covered in a psychic reading as everything is in your aura and is the energy that is being read. Psychic readings would also cover the future.
I've had people say they want a future reading, a relationship reading etc and it's actually a psychic reading they mean, as over the years different psychics and mediums have called them by different names, usually to make them stand out from the rest.
