I saw an old movie on youtube ,it said the movie was banned in some countries when it came out. Maybe because anti tv and microwaves etc.
The story line of a mother from a another planet comes to earth on a mission . she creates some sort of thought bubble she steps in to transports herself here.
While on earth she can’t eat the food , junkfood is toxic. To sustain herself she  has to be  around a new born baby because they are a pure energy. She visits a hospital to see the new born.
She makes phone calls back to her home planet by standing in water at first in the town  water fountain until she is shown the bathtub. by a guy who helps her. it ended with her finding her son and him swinging in a tree swing or something. .
