nightmare? dream?

I just woke up from a dream

After receiving the news that my brother is in the hospital. I just felt my energy drained from my body. After talking to my dad on the phone and my mum online... I just couldn't help it... and I tried to go to sleep...

--------Dream? Nightmare?--------
It was dark... cold... I was going somewhere... to my old school...
As I left the last place which had the only source of light... Everything started to become dark... cold... There was the moon and I could still see where I was going. Then... the clouds covered the moon... everything was dark...
It took time for my eyes to adjust itself... I could still see the walkway to the school hall... and then... to a dark corridor... I just had to go through that dark corridor... hoping either my eyes will get used to the darkness or the moon will reappear from behind the clouds... but when I started only a few steps through the corridor... and saw the chain doors in the darkness which closed the stairway... I started to become scared... I walked backwards out of fear... and fell backwards as I missed my footing... only to be caught by someone familiar... it... or should I say she... said... 'It's alright, I'm here with you'... and there is where I woke up... surprised... frightened... disoriented... my mouth was dry and just had to get out of bed to get a drink of water...
--------Dream? Nightmare?--------

I feel so helpless... I feel if only I can be like that person in my dream and tell my brother that he'll be alright because I'm there... If I hadn't come here... I just know that he won't need to go to the hospital... If only... ='(
