multiple personality disorder in dreams

Ok so i am a 18 year old male. i consider myself healthy i do fitness. And lately i've been taking a supplement Called "ZMA" and I've been having really vivid dreams that i can recall really good. I went online to search and more people have these "lucid/vivid/weird/crazy" dreams those are terms they used to describe their dreams. I on the other hand would describe my dreams as Vivid and sometimes weird. But last night i went to sleep and a had a good dream that ended kind of weird. Because i am studying abroad very far from my family adn i dreamed that they came to visit me on vacation. it was fun i did a lot of fun things with them. but at the end of the dream when they were suppose to be heading back home i was in a room with my mom and sister and my dad was in a another room sleeping. and i wanted to go wake up my father my mom said to me " let your father sleep you may make him angry" i asked why, she said because of the argument you guys had in the park, i told her witch park and witch argument. so that was the first thing that happend in my dreams that i couldn't recall. next she told me that i was very loud and screaming acting like a child at the park that was the second thing i couldn't recall inside my dreams self all of this is happening inside my dreams. and lastly she told me while i was playing like a child and being loud i said "i like to play" "my mommy aways wanted me to play" "but i was never into playing" and i a 18 year old playing with kids and acting like one then i woke up. and i was overwhelmed.

i felt like something wasn't right its the first time that i did things inside my dreams that i cannot recall and someone else have to tell me them. i'm afraid i'm showing traits of multiple personality inside of my dreams. that maybe my consciousness knows but i dont..

So i would love it if someone could clear it up or try to explain what is happening.. or even diagnose me with multiple personality disorder.. i'm not afraid i just wanna know whats happening..

P.s: i also have a lot of problems with memory impairment i forget small things and big things /unimportant and important. even recent things. but i am able to fucntion in daily my daily life.. but i often forget about agreements i have made or appointments i have.

Dreams are only dreams. Don't worry about "weird" dreams. I also don't see anything related to DID or multiple personality disorder in your description.

Thank you very much!
