Hello,
This is a good question, because there are a lot of frauds in the spiritual industry unfortunately that tarnish the reputation of legitimate practitioners. So, is it real? The short answer is yes, although many psychic abilities fall into the category of UPG, or Unverified Personal Gnosis. There are exceptions to this, although the exceptions are somewhat rare. Some mediums practice physical mediumship, which is more demonstrable and occasionally even apportations will happen. An ‘apport’ is when a physical, tangible item will materialize out of thin air (or, from the spirit realm). Other demonstrable evidence can be found through Remote Viewing, a type of clairvoyance (at least in my opinion) where the things experienced can be independently verified and confirmed as true from a third party.
There are also times when a psychic might have a vision of the future, which later comes to pass exactly as predicted. How are these things possible if it is not a real phenomenon? A lot of ‘ghost hunters’ use equipment to scientifically measure spiritual activity, such as an EMF detector or EVPs (Electronic Voice Phenomena). There are also people who capture evidence of items moving or spirits materializing, although this is much more rare.
Due to the nature of most psychic experiences being UPGs and ‘unverifiable’, it ultimately falls back on the power of belief, which you are free to choose. However, perhaps the best way to ‘get a taste’ of psychic abilities is to try divination for yourself and see what happens.
