Alien abductee?

How can you tell dream from the reality? Most of the time, our dream could be so real that we will doubt whether it actually happens. However, for people with their right mind will know for sure that it is only just a "real" dream. But for those who convince themselves that the incident is so vivid that it can't possibly be a dream and it must truly happens to them.
Of course, no one could actually answer this question. But some psychologists believe the phenomenon of alien abduction to be all in mind, and not an actual physical experience. Besides, some experienced hypnotists can create such experience to hypnotized people through progressive induction.
There is one good example describing the danger of mind control. When you meticulously ultizer people's rare and fragile experience, they will accept you right away without second doubt. Just like when you do an experiment on a frog- if you put it in boiling water, it will jump right away out of the pot; conversely, if you put it in cool water, and slowly heating up the pot, it will eventually die in the hot water because it's too late until the frog finds out it is in deep trouble and has become too weak to struggle a bit. This can explain why the leader of HEAVEN'S GATE CULT can easily persuade his people to follow the "death path" with him.
(well....the funny thing is the "frog experiment" above i found out could be applicable to many cases in our live. And the idea is similar to the book I just finished - "who moved my cheese?".....i can talk about it later!)
