Recurring Dream Help!!!

I've had 2 kinds of recurring dreams throughout my life. Actually they would be more accurately described as dreams with recurring subject matter. The first involves tornados. The second I refer to as end of the world dreams. They come in different forms. Some involve strange cosmic events like being able to see planets and other moons clearly and close up. Others have strong religious connotations, while others are extremely violent and war like. I don't know what my dreaming these things means, if anything, but I'd like to get your opinion. One of the first I remember involved me chasing a strange yellowlight around my house that lead me outside and manifested into the holy ghost. I don't remember clearly the message that he was giving me, but it seemed peaceful, like saying I was saved. I consider it an end of the world dream because in the dream my intuition told me I was being spared an ugly fate that would affect the rest of the world.

Another sort of revolved around the millenium theory, I was in my home on New Year's eve and was drawn out by some commotion. I look up in the sky and there are planets, and moons that shouldn't be visible, let alone close enough to count the rings on Saturn. It was as if the universe was closing in on itself and though it was cool to see the sky, there was a sense of impending doom. This is the most common type of end of the world dream that i have. It's always different, what celestial bodies can be seen, sometimes Jesus comes down to start the rapture, etc. But the main elements are always there.

The last main variation was very violent. It involved an army of primitive people coming after my family and several others in a desert after a large flash of light and several moments of darkness. Then a dim red light came on in the sky, like back up lights during a storm, and this is when they came after us. They were heaving spears and other weapons at us while we're trying to escape them, as well as a deadly acid rain falling from the sky. They're very scary and unerving dreams for me to still be having, not to mention when I was younger. If anyone has some insight on what these may mean, aside from the obvious implications, or why I would be dreaming about this stuff, I'm just a normal person, not extremely religious or gifted in any way. Please share your thoughts and opinions.
