I shall post some easier ones, and see how you fare with them.

(1) Riddle me this: I come in darkness, but fill the mind with light. I bring enlightenment to some, while gripping others in the hand of fear. With me it can be a journey of inexplicable joy and sorrow. What I will show you will often be unreachable. Journey with me and what you see may haunt you. Journey with me and you may never want to return home. Journey with me and you will never know when it will end. What am I?

(2) Riddle me this: What word can be written forward, backward or upside down, and can still be read from left to right?

(3) Riddle me this: Samuel was out for a walk when it started to rain. He did not have an umbrella and he wasn't wearing a hat. His clothes were soaked, yet not a single hair on his head got wet. How could this happen?

(4) Riddle me this: There are 20 people in an empty, square room. Each person has full sight of the entire room and everyone in it. If you are not allowed to move in any way (other than your eyes). Where can you place an apple so that all but one person can see it?

Again you have figured them out; well, all except #2, and it is not an acronym, it is a four letter word, and when a gunslinger gets shot it's usually high--that's the only clue you get.
