From the Pew Research Center:
Most American adults self-identify as Christians. But many Christians also hold what are sometimes characterized as “New Age” beliefs – including belief in reincarnation, astrology, psychics and the presence of spiritual energy in physical objects like mountains or trees. Many Americans who are religiously unaffiliated also have these beliefs.
Overall, roughly six-in-ten American adults accept at least one of these New Age beliefs. Specifically, four-in-ten believe in psychics and that spiritual energy can be found in physical objects, while somewhat smaller shares express belief in reincarnation (33%) and astrology (29%).
But New Age beliefs are not necessarily replacing belief in traditional forms of religious beliefs or practices. While eight-in-ten Christians say they believe in God as described in the Bible, six-in-ten believe in one or more of the four New Age beliefs analyzed here, ranging from 47% of evangelical Protestants to roughly seven-in-ten Catholics and Protestants in the historically black tradition.
