Unwanted Dream

What the different between dream and nightmare, is it same?

At one night, I've a very bad dream,,,
in that dream, I saw one person whom I really love give me one message
If he will be die soon..
He told me to get ready for this...

I really not want it. I wont he leave me... Its better if I'll go die first...
but at one side, I looking his face... and he was look very happy...
is he really want this? is he really want to leave us? I dunno...

Finally, I wake up from my bed...
it feels so real for me, but I'm glad it was just a dream... a bad dream or nightmare exactly....
I hope if its not a sign for me...

after that I open up my laptop, and turn on my mp3  song playlist..
hmm, its just be another mementomoria... I see one titled song... Firasat by Marcell...

kemarin kulihat awan membentuk wajahmu

desah angin meniupkan namamu

tubuhku terpaku

semalam bulan sabit melengkungkan senyummu

tabur bintang serupa kilau auramu

aku pun sadari, ku segera berlari

cepat pulang

cepat kembali, jangan pergi lagi

firasatku ingin kau tuk cepat pulang

cepat kembali, jangan pergi lagi

alirnya bagai sungai yang mendamba samudera

ku tahu pasti kemanakan ku bermuara

semoga ada waktu, 

sayangku, ku percaya alam pun berbahasa

ada makna di balik semua pertanda

firasat ini rasa rindukah atau kah hanya bayang

aku tak peduli, ku terus berlari
