FYI: Hallucination is a process of getting detached from reality and perceiving something that is not present. It could be hearing voices, seeing things, perceiving strange smell, sensing odd taste while eating/drinking, or feeling certain sensations on body like being tickled or insects crawling etc, without the presence of stimulus.
Coming back to the query, I see that you are wondering if its hallucination as you have mentioned in the headline. Our mind keeps wandering all the time in Past-Presense-Future at different intervals, but to say if its hallucination or other condition we would require more information from your end w.r.t
-how much is your daily routine getting affected with the mind dwelling in past and future?
-what are the things that you think about of past and future?
-what do you mean when you say there is no control over body? are there any physical changes like palpitations, numbness in body etc?
-when you say you laught at it, is it in mind or aloud irrespective of where you are?
With these information provided we could help you more with your current situation.
However, with the little information provided by you, what we can suggest is, set aside some time for yourself. Analyse if there is anything that is bothering you from past and if there is any worry about future, try to resolve those issues. Practice mindfulness to relax your mind. Reach out to our experts if you need more support. If the condition is worsening consider consulting a Psychiatrist.
