If it was dissociation it would be something that has been going on your whole life. Everyone dissociates to a certain point normally anyway such as geeing so interested in a movie that you dont notice what is going on around you, driving the car and thinking of other things then focused on the mechanics of how to drive, daydreaming. A person who dissociates beyond the normal rage is a person who has experienced a trauma or abuse that they were not mentally capable of handling.

If being in the jury was the cause for dissociating beyond the normal rage you would have felt this way at jury and after jury duty on up to the present. Dissociation beyond the normal doesn't have a sort of incubation time frame. It happens during the situation and after.

Since this has started not a month ago but a week ago my guess is that this is a medication reaction. I say this because you started feeling this way after starting medication.

Talk with your prescribing professional - the dosage may be too high or that medication may be one that you can't take. Also this spacyness and out of touch is usually an antidepressant side effect. Anti depressants are a suppressor which means they shut down or slow down the brains chemicals. So again talk with your prescribing professional. Dont be afraid to ask him/her questions especially when going on meds that professional should be telling you what the medication does and its side effects.
