OCD is an anxiety disorder. For whatever reason, the brain takes something that causes anxiety (for this, it may be the fear of being alone), and morphs it into something huge. To reduce that anxiety, people compulse- so for you, that would be the repeated touching and saying his name. It isn't that the brain isn't processing the information correctly. It is. It is just taking that information to a whole new level. The part of the brain that is the "satisfied" component is not making the proper connections, therefore resulting in the "getting stuck".

To me, this sounds like OCD. not dissociation.
