There has never been a concrete answer to the universe or life. What exists are philosophies which serve to make the believers feel like they have achieved some knowledge that others do not have. They confuse themselves and try to confuse others with ambiguous words and statements like what is real and what is unreal. They will continue to confuse themselves and others with a web of words that sound intelligent and confusing at the same time. It's very easy to confuse others so that you gain some feeling of superiority over others.

There is no point in questioning if you are real or not. No matter what kind of philosophy you have to explain that this whole existence is not real, you are living each moment right now. Try to take a razor blade and run the blade across your body if you are not real. Everyone of us are as real as it gets right now. When we cease to exist there is no reality for us but the people who live are sharing a common reality of life which can intersect with each other or exist in parallel.
