Unfortunately, they do not teach things like that in Sunday School. Meditation, dreaming, and altered states of conciousness are accepted and an expected part of other beliefs like Buddhism and Shamanism.

Also, when talking about visions and dreams and such, many Christian churches dismiss them as belonging to the age of the apostles. I've sat in services and heard sermons to that effect. BUT, I've also sat in on many Full Gospel or Pentacostal services and heard just the opposite.

You know the mindset. If dreaming is accepted by the buddhists then it must be an evil thing and not proper for a young Christian to become involved with.
