Is it normal to be afraid of most things?

Well to give you a hint of what I mean, there is a long list of things I am afraid of. The thing I'm afraid of the most is spiders, I know most chicks are but when ever when I see them on TV I flinch in fear, China dolls my mother has one in her room lol, big dogs, big rooms even sleeping in them, silents as in being in a room and its quiet but only at nighttime though, darkness, horror movies, horror music, lightening at night but love them in day time, Looking at windows at night for longer than five seconds in case something look back at me, random noises at night, I imagine that an earthquake might happen, well considering I was in one but I think about having another one big one, I fear of living alone or dieing alone and death itself, I'm always thinking of scenarios where something jumps out at me or if I'm in the car, we may crash or just being in the house and something big crashes through the roof. I know its a bit much but is it normal to fear most things and think up scary scenarios?
