What the heck is really going on???

Okaye... i've not been sleeping well for this 4-5days. I am having nightmares daily... and it's super damn scary, gory, supernatural and weird. i said supernatural is because in my nightmare, everything happened so supernaturally that i can't even explain it with science... Well... last night, i woke up a few couple of times. More to... Struggling to be awake... Okaye... i'd love to tell u guys all my nightmares.. But... the weird thing is... i don't remember what happen to me in the nightmare, i only know that it's gory, frightening... Well, i woke up 3 times AND when i get back to sleep, it's another nightmare... i wokeup at 5.30am this morning, and found my bedroom door opened... and i was shocked... and i was like.. "Who the heck came into my room while i was asleep?"
i remember me closing and locked the door before i sleep...
and i ask my family members if anyone did came into my room, but no one did other than me, myself. Anyway... i'm so gonna put a notebook and a pen beside my bed... So whenever i'm being shocked awake by my nightmare, i can write it down quick before i dont remember anything...
Seriously... i was quite affected by all these nightmares today... i woke up with the moodless expression on my face and with this moodless expression to school... Well, i was feeling super uncomfortable about me not being able to remember a single thing abt all those nigtmares... When i reached school today, my teacher came to talked to me because she knows somethings isn't right... So i nodd/shake my head when she ask me questions...
And seriously, i want to be positive and i believe i wont have nightmare again from tonight onwards.
And thank God that my alarm clock woke me up from my nightmare... I only remember i was crying in the nightmare and i was struggling to actually wake myself up from my dream...
Amazingly, i have the ability to actually wake myself up when i'm dreaming/having nightmares...
Don't ask me how i did it... i don't know too.. But i can tell u guys 1 thing, i struggle to wake myself up everytime i'm having nightmare...

p/s Zining had the worst nightmare ever...
p/p/s I spoke in tongues when i was shocked awake.
p/p/p/s My brother told me jokingly, maybe i was sleepwalking, that's y my bedroom door was opened.
