first to answer your question.....

yes many people have DID and do not know they have it.

that said there is no way to tell if you have it based on not remembering and suspecting switching suspecting dissociating...

let me show you what I mean......

here where I am located dissociating (feeling numb, spaced out, disconnected......) is just a reaction to a trigger. a trigger is anything positive or negative that causes a person to have their symptoms.

in other words its kind of like emotions.....

you know how if someone says something you dont like (trigger) you automatically out of your control feel angry (reaction)

thats what happens....

something happens (trigger) to make a person feel numb, spaced out and disconnected in other words dissociated (automatic reaction)

a person does not have to have DID to dissociate....Dissociation is now part of many mental and physical health problems.....

examples a person with PTSD can have their dissociation symptoms. a person with bipolar disorder can have dissociation symptoms, a person who has sleep problems can have dissociation like symptoms. a completely normal person can also have dissociation problems just due to their stressful every day lives...

switching just means you change from one one thing to another...

normal people change their moods, minds, emotions, what they say and do on and off all day long as they go through their normal days.

sometimes this normal switching of moods, changing ones mind, changing behaviors, emotions can appear to be extreme mental disorders like psychosis, schizophrenia, bipolar disorder, sleep deprivation, eating disorders,,,, gosh everything and anything that is normal can seem like switching personalities.

theres more to being DID then just dissociating and switching.and not knowing or knowing that its happening. theres whats called other accompanying symptoms that only treatment providers know about.

my point is you could wonder and guess forever and possibly end up misdiagnosing yourself with DID, presenting what you think may be DID and a treatment provider end up misdiagnosing you with schizophrenia because you may be unconsciously going on your wonderings and guesses. (this actually happened to someone that I knew their actual diagnosis turned out to be a mild form of epilepsy, borderline, brief episodes of narcolepsy, in other words she was having mild petit mal seizures, mood swings and moments through out her day suddenly fall asleep for only minutes at a time. but for about 5 years because she was worried about being DID and was "projecting" this her treatment providers diagnosed her with fictitious disorder imposed on self and schizophrenia.)

my suggestion is let your treatment provider know you are wondering whether you have DID. they can get you set up for actual diagnostic evaluations. its a very long process has more than one test and the tests are not found on line neither the names nor samples.
