Your mother's a psychic? So you grew up in a home with profound mental illness, and now are convinced manifestations of her mental illness describe your own reality.
While I've experienced immediate-term precognitive experiences all my life, I don't believe anyone can do it on-demand as with so-called psychics. If anyone could, they'd be repeat lottery winners and professional gamblers.
I think information is being transmitted and received in some as-yet undescribed way. Thoughts are afterall just electrical impulses. In the same way both the US and USSR developed working psychotronic weapons which could transmit erratic signals into target brains of people wrecking havoc, I think some of us have the specific genetic and physiological makeup enabling us to receive electrical impulses at a distance. Our enviroment is filled with EM signals, radio waves, microwaves, etc. that some people pick this clutter up from time to time should come as no surprise when everyone's brain is a transmitter as well as receiver.
But there's nothing supernatural about it.
Due to genetics, some humns can see partially into the ultraviolet light spectrum giving them very good night vision. But they aren't superheros or in possession of some supernatural ability. It's just genetic variation. So just as a few can see into a spectra of light most can't, some can probably pick up EM signals while most cannot.
