I agree with you Alisa, anyone can connect to the spirit world, should they wish to do so. It is obviously easier for some people, than others. Those who are more sensitive and their power of:
clairvoyance (the ability to gain knowledge primarily by visual means.Clairvoyants may also perceive types of energy not normally perceptible to humans, such as spirit energies and auras),

clairaudience (the ability to hear things that are beyond the range of the ordinary power of hearing),

and

clairsentience (means 'clear sensing' in French, and is the faculty of superphysical sense perception. It overlaps with other abilities such as clairaudience and clairvoyance, and is the psychic perception of smell, taste, touch, emotions and physical sensations, registered either internally or externally)

is more developed, will experience more of it, more frequently.

As the majority of people appear not to want to do so, and are not used to experiencing such phenomena, it is then deemed 'paranormal, unexplicable,weird'.

There is nothing 'paranormal' in this world, just our limited understanding of Nature.

We live in a multidimensional space and are completely surrounded by spirit at all times, whether we are aware of this or not.
