I weaken all men for hours each day. I show you strange visions while you are away. I take you by night, by day take you back. None suffer to have me, but do from my lack. What am I?

A 300 ft. train is traveling at 300 ft. per minute and must travel through a 300 ft. long tunnel. How long will it take the train to travel through the tunnel?

You breathe out, I breathe in. You let go, I breathe out.
What am I?

I’m normally under you. Take away my first letter, and I’m normally above you. Take away my first two letters, and you normally can’t see me.
What am I?

I can fly but have no wings.
I can cry but I have no eyes.
Wherever I go, darkness follows me.
What am I?

Die without me, Never thank me.
Walk right through me, Never feel me.
Always lurking, Never seen.
What am I?

Ice melts when heated up. But I solidify when I’m heated up. What am I?

I look flat, but I am deep,
Hidden realms I shelter.
Lives I take, but food I offer.
At times I am beautiful.
I can be calm, angry, and turbulent.
I have no heart, but offer pleasure as well as death.
No man can own me, yet I encompass what all men must have.
What am I?

I start with the letter “e”, I end with the letter “e”. I contain only one letter, yet I am not the letter “e”! What am I?

I have a big mouth, and I am also quite loud! I am NOT  gossip, but I do get involved with everyone’s dirty business.
