It is commonly accepted that we communicate a great deal with metalanguage, i.e., subtle cues of body language, facial expressions, eye movements, inflections with the words we use, etc. We can pick up information from others without being aware of doing so. This would not constitute mind reading, but rather, it would be subconscious processing of subtle cues that we aren’t necessarily aware of. A well constructed experiment would control for this. Your teacher’s experiment may not have. She may have given subtle cues that she was not aware of giving and that you were not aware of processing.
Thanks, that explanation seems plausible, and it makes me feel better. I’ve noticed that unexplained loose ends such as recalling that ESP experiment opens the door to my crazy suspicions about reality. Simply brushing-off unexplained events is no longer enough; I have to actually satisfy myself that the scientific/atheistic model of reality still works. I don’t have the same instinctual faith in normal reality after experiencing psychosis.
Also, I think responsible parties like governments and media should be more active about debunking. For example, the UFO field has become more ridiculous after the Air Force walked away from Blue Book. Society in general seems to be less rational and scientific than it was in the 1950s and 1960s.
