My Question is , Is this world: matter… 'solid reality' or what we think we 'see'; merely an illusion? Like i mean - in dreams we think that our dreams are reality but the truth is what we see in dreams is actually what our brain makes us see and makes us think that this world is reality but in truth we are only dreaming in state of sleep and that dreamworld is not real , similarly , we have to die someday , so is this World , Matter a Reality or is this world just an illusion just a vision which our brain makes us see ?? Is this World a state of Illusion ? everything we experience Happiness , sorrows , memories , are these things just merely an illusion which our brain makes us see on the inside ? and this illusion will only be removed when we wake up after our Death ?
