I emailed the thread to a professional friend of mine because I wanted to understand better.

he told me from the last post it sounds like you are trying to figure out if deja vu feelings is co consciousness and integration. sometimes people he has been in contact with use the phrase - alters catching up with me - as a way to explain being integrated.

He also said integration feelings are not like feeling deja vu.

Integration feelings is just remembering what you have forgotten like you have put your keys down somewhere and forgot where you put them and suddenly you remember where they are.

an example of When alters are integrated or as he sometimes refers to it as - the alter catching up with the person is like someone not knowing they were raped and then can remember parts or all of the rape experience.

Deja vu is when the person has never experienced something in any way consciously or unconsciously and get the feeling that they have heard or done that before. for example riding a bus and going down a completely new street and feeling like I have been there before.

What causes deja vu feelings is because there may be one thing that matches with another situation for example by eyes happen to record seeinng a window that looked like a window of a familiar house I have been in before. Even when we are not paying attention to our senses the brain is still taking in what is around the person. When seeing the window that matches with a window of a house I am familiar with the feeling that I have been there before happens.

he said having this happen is not limited to people with DID every human being experiences deja vu because from the day they are born to the day they die the 5 senses are automatically taking in information and the brain is continuously matching what is being experienced through the 5 senses and matching it with the experiences and memories that person has had.

Integration (or as some people call it alters - memories - catching up) and dejavu are completely unrelated and different.

Hoped that has helped.
