A dream in a dream

Been feeling odd lately, which resulted in a weird dream too, which happened last night. It was a dream within a dream. The feeling was like that i was relieved that i had waken from a dream, only to find out later that it was still a dream. And i get confused (even during the dream).

This has happened many times before too, but this time it was so obvious that after i finally wake up to the real "reality", i could still memorize the dreams very clear. It was kind of a nightmare, perhaps the reflection of my negative thoughts which resulted in a scary dream. The first dream was about me trying to avoid traffic polices, and found out that my name was blacklisted. Suddenly i was awake (which actually not), and i felt very relieved that it was a dream..., a while later i saw through my window, view of smokes everywhere. The smokes burst up very high, which look like pillars of smoke everywhere. There are other things too happened... I saw houses were like damaged, and without roofs. It looks like an after war scene, and at the same time i felt the temperature was getting hot (I later realize this might be because the "real" room temp was quite high and i was somehow dehydrated). Back in the dream, i thought this scene must be something like the end of the world, it felt so scary, and real. Then i awake. Thank God for real.
