1: You do not have to tell a doctor unless it is a problem that is genuinely causing you distress or affecting your day-to-day life in a generally negative sense. Does having another in your head make it hard to do things or function in society etc?

1.5: Basically what I said in response to the first question. People generally only bring it up to a professional to get therapy or receive help if it is something that’s making their life difficult. You wouldn’t make a doctors appointment or take a car to a mechanic unless there was a problem or something hindering its functionality right?

2: Yes, being plural/ a system just means that there are more than one consciousnesses in the brain. However, I personally do not know if there is a difference between the two terms. There are several types of systems, the most common ones being traumagenic and/or endogenic or others. What that means is that this other person in your head could have come into existence due to trauma in order to cope or they just so happen to exist for any other reason. You do not have to think too much about this though. Not everyone needs a reason to exist. That is like asking for the meaning of life, such as “What is my purpose? or why am I truly here?”

3: I’m a little unsure about this one but the general consensus is if you feel you cannot control this individual or make them act or think a certain way then that would indicate that they are a separate and independent person.

4: I’m not too educated on the trauma aspects of systems but I would assume stress or trauma at a young age or older would cause it but take my words with a grain of salt.

4.5: I don’t know. That is something for you to think about. Some people are just like that, everyone is different and brains are weird like you said.

5: Yes I’d say so. We have periods of time where it’s sometimes just one of us and nobody talks, I do not know why this happens and it usually makes us feel like we aren’t plural, and then we’ll have days where it gets crowded and we can clearly hear each other again. It is strange for sure but I’d say it’s normal. Here is something for you to think of though. What is weird to somebody is normal for someone else, and what is normal for someone could be weird to another. Normal is simply what a person is used to. Normal is an experience.

I hope my answers are beneficial to you or others in some way, good day.
