Nope. Pure, 100%, unadulterated quackery. Fraudulent snake oil sold to the gullible.
At least the ones who claim ridiculous abilities like "astral travel" and such are charlatans. There are also a lot of professional "psychics" who honestly believe they have an ability -- they mistake normal intuition and lucky guesses as "evidence" of their "powers", and make a career (literally) out of helping others with their "insights".
Even charlatanry has gone downhill in these degenerate times. Victorian mediums would at least put on an entertaining show with trumpets and everything, not just sit there vacant-faces and spin a tale of "astral travel".
