How does lightning occur?

The positive and negative electrons split in the cloud

Positive going to the bottom of the cloud and negative to the top.

Since you are made of negative electrons, you attract the positive electrons to you causing you to get struck by lightning.

The ground has negative electrons too!

This will shock the ground and end up shocking you as well, since the ground and you are connected.

Lightning and thunder are connected! They do happen at the same time. The reason why the thunder travels later than the lightning is because you are away from the lightning and the sound waves are just getting near you

B.) How are thunderstorms dangerous?

Thunderstorms are dangerous because they give off positive energy. If you are standing outside while a thunderstorm is in session, you could get shocked since you are made of negative energy and attract positive energy.

If your hair is sticking straight up, you are about to be struck by lightning. Crouch down and cover your head next to your ears and prepare for impact.

You might ask, "Why can't I just run from the lightning?" That is true, but since you aren't faster than light itself, you will still wind up caught in the storm.

Avoid this by staying inside.

Hope this helps <3
