The question could lead to a long drawn out philisophical debate. On the one hand, using the assumption that what we see is there, On the other hand, using the argument (as some do) that nothing truly exists. That everything we see is simply a construction of the mind. There is no way to truly prove either argument.
It depends on how you define "sound". If you define "sound" as "pressure waves", then yes it exists outside your mind. (Arguably, it exists outside your mind no matter how it's defined... in my mind, for example. If your philosophy teacher disagrees, accuse him of being a solipsist; that should start a discussion that will derail your class for the rest of the period.)
An absolute reality is a reality in relation to the divine mind.
Dreams do not cause anything, they are merely thoughts passing through the sleeping mind. Dreams exist only within the mind (brain) of the dreamer and have no power to influence anyone or anything outside the dreamer's own body.
The absolute value of any number is its distance from neutral 0. With that in mind, the absolute value of -158 is 158.
When you sleep, you don't actually see anything. Your eyes are closed, and they are blinking quickly. The pictures you see are not actually images but they are in your mind.
Solipsism is the philosophical idea that only one's own mind is sure to exist, and that anything outside of one's own mind may not exist. It can lead to skepticism about the external world and the existence of other minds.
Yes, when part of your brain dies then part of your mind no longer exists ... as in a stroke.

The behavior of the mind. The status of which is compared to what is collectivelly considered normal. Anything that outside of this accepted level called normal is considered, "mentally abnormal behavior"
Idealism refers to any philosophy that argues that reality is somehow dependent upon the mind rather than independent of it. More extreme versions will deny that the "world" even exists outside of our minds. farhad
Hume believed that knowledge comes from sensory experience and that we cannot have absolute certainty about anything, while Berkeley argued that reality is fundamentally mental and that our perception of the world is shaped by our minds and God. Berkeley's philosophy is idealism, meaning that everything exists in the mind or is dependent on it, while Hume's philosophy is more empirical, relying on observable evidence for knowledge.
The term is "conceptual" which refers to something that exists in the mind or as an idea without a physical form.
