Disruptive sleeping pattern

My sleeping pattern is so screwed lately. It started since the death of my grandma. I don’t know why but probably her death affected me badly in some ways without me realising it.

I would normally sleep around 10pm+ or 11pm and woke up in the middle of the night around 4am+ just for a short while and then goes back to sleep. I know the exact time because I can see my clock glowing in the dark. Then I will wake up as usual around 6am+ for work except for Saturday where I usually wake up late.

Apart from the sleeping pattern, I also had some scary dreams. In one dream, I was longing for someone to come back but I knew that the person had already died. I refuse to accept it and eventually burst out crying and I cried for real! I woke up shortly after that.

And last night, I dreamed that I was about to be admitted to the hospital. I can only recall some part of the dream now. I think I was brought to the hospital in an ambulance and was sitting on a bed. I don’t feel sick or anything, but when my dad asks the nurse if I can go home she said I need to be admitted because they are some swelling on my mouth or face. And I woke up after that to get ready for work, apart from waking up earlier at 4am+.

I know something is bothering me that causing me to experience all these but I just don’t know what it is. It could be something physical, emotion or feeling but whatever it is... I just want my normal life/ sleeping pattern back. *sigh*

Maybe I just need a break!
