How can i be sure that i am awake?

~~~ The moment that you are 'sure' that you are awake, you wake up!

Again!

Being 'sure' of anything is a mental error, a 'flaw'.

Just Pay attention!

Never be 'sure', never 'believe'; therein lies madness! *__-

Define awake...actually your question makes a lot of sense.

The dream state is quite compelling, and sometimes I have to ask myself.."is this true, or is it the physical life I have to deal with?"...who knows?

Don't worry about that. You should do crazy stuff you'd think too much about when you are sure you're in a dream. Don't waste dream power.

Look at your hand, or a clock, or a painting--some Heideggerian object as existing in time--look away, look back--if it's changed, you're dreaming. Related: "The Master of Lucid Dreams," "Watch Your Dreams," "The Path of the Higher Self." http://dreamstudies.org/2015/02/04/lucid-dreamers-...

Walk to the end of a cliff and if you stop than you are awake.

If you are feeling hungry or thirsty you are surely awake.

When you are truly awake, you will feel like you must be dreaming ~

If you close your eyes, everything may look dark. See the many wonders in this world. Don't show a deaf-ear and blind eye. Smell the difference in the atmosphere.

The best way is to look at your hands. Can you count all fingers? Do you feel pain when you bite your hand? Otherwise you are probably in a vivid dream.

You cannot. That idea was first advanced by Descartes 500 years ago and remains a conundrum today.
