You people aren't describing a bad trip at all. All that is is anxiety and nervousness caused by the trip. The trip will destort time and your mind will revert to a more primal primitive state. Senses are heightened. We are not used to it, so we do not know how to react. A bad trip is when you lose total touch with reality. As in not knowing what, where, when, why anything exsists or is. It is truely terrifying!
