I do not want this to be misleading.It is not the door as a portal to the other side.Someone else did that.
Remember Uri Geller and the spoon bending or perhaps you have seen things flying about related to poltergeist which were discovered to be coming from the energy of the person herself/himself?
In general,movement of objects by the power of the mind or will power alone is considered to be psychokinesis(PK.)Uri did it by bending spoons.My psych nurse friend Roberta,I told you about before when she saw a classmate's new car(clairvoyance), after a few sessions at the lab developed her PK ability as well.
One day she whispered ( This type thing was not generally well accepted in our circles.)that she had opened her closet door that morning.I wanted a demonstration so we went after class to my apartment.There was a very thick two sided sliding door to the closet in the bed room.Either side could seldom be opened one handed.Roberta lay quietly on the bed for a few minutes saying before that she was centering,clearing her mind and then would concentrate.I am sitting quietly thinking "Yeah sure.That is way too heavy"
After about 8 to 10 minutes,one side of the door began to slowly slide.It picked up some speed and wham it was completely open.I was amazed.She did it.(In spite of encouragement however she was never able to mop or wash my dishes which would have been a welcome addition.)She did grow and expand the moving of objects.That demonstration was the heaviest thing she ever moved.The next time she told me of an accomplishment,I believed.
