Hi Valash,
I've had this question in a similar vein when I first started blogging for the Connection.
The hallucination is so vivid and feels so real that it is possible to feel you have been "pushed" by someone or something that has pushed you. Of course this has not actually happened, yet you're convinced it has, possibly due to a self-fulfilling suggestion that you've been pushed.
People have had hallucinations where others are stabbing or spitting on them, and if you're not aware that this isn't real, you could think it's actually happening.
Regards,
Christina
