there is no widely recognized or scientifically established concept known as "Chronal Dissociation" in the field of psychology or psychiatry. It is possible that this term has emerged or gained popularity , or it may be a term used in specific fictional or speculative contexts.
If "Chronal Dissociation" is a term used in a context outside of established scientific literature, it could be associated with fictional works, role-playing games, or speculative discussions related to time travel or dissociative experiences. In such cases, the term might carry a unique meaning within that specific context, but it would not represent a recognized psychological or medical condition.
If you encountered the term in a particular context, it would be essential to clarify the source or provide more context to understand its intended meaning accurately. As i am not an expert, I do not have information on developments or new concepts that may have emerged after that date.
