I don’t. I have no idea if I am dreaming now or not.
Dreams are perceived to be things that we cannot feel and can only ‘dream’. They are not real. Some people, however, perceive them as ‘gateways to knowledge’; signs.
I don’t even know whether the ‘dreams’ that I dream are even really ‘dreams’. What if they are the real world? This blog post that I am typing now is just nothing but a dream, but perhaps, what we think is ‘dreams’ is actually our real life? Simply put, what if our real lives are actually the ‘dreams’ we perceive them to be?
What happened to all those ‘achievements’ I achieved? Were they all just a dream?
The ground I feel beneath my feet is solid, I can walk on it, jump around. I can canoe, I can do all sorts of exercises and then, I sweat. I can feel all of it.

All those things that I have done, the ‘years’ I have lived. Don’t tell me it’s fake! Don’t tell me that when I ‘die’, I would just be ending my ‘dream’!

People talk about death, they view it as ending something, if we are all dreaming, wouldn't it just mean we are kicking up a big fuss over nothing? In addition to that, why worry about our post-existence when we did not have to worry abotu our pre-existence? We were non-existent then, only when we come out do we start to fear death. Why do we? Why worry about not existing when you weren't existing before?

So how do we know that we aren't dreaming?

Haha, pinch your thigh.
