I can guarantee you it happens my friend. People accidentally curse other people all the time, and many children will even invent thought-forms as Imaginary friends. You could even take a look at poltergeists, because they are usually manifestations of an individual going through emotional dread. There also seems to be some non-voluntary energy movement like when a person orgasms that seems to release an uncontrolled energy bursts that is inherent to the action rather than needing to be thought about. Energy can also be given by accident through the use of people interacting with certain constructs such as names, or sigils, and acknowledging their presence, and existence. We have many different cases of people’s energy accidentally being used, it’s very interesting that you don’t believe in it though, especially when intention, will, and emotions controlled this energy which people clearly most of the time don’t have under complete control.
