I'm really creeped out as I write this. This dream is really freaky...?

[Nickie the socccaaa star!]

I'll relate as much as I can remember:

I start out in some sort of sitchuation where things are very hectic and me and my family and a couple of people I don't know are struggling to stay alive.

The next moment we wake up in a bright beautiful garden in a gazebo type thing. I cling to my mom and the rest of my family and hug them. And then I follow my mom as we go to eat food off this table in the garden. I'm scared about dying. And I say "I don't want to die again!"(Exact words) and I keep glancing at the clock. I think to myself that I have 10 minutes. Then I say "What if in my third life I have completely different family! I don't want to go." I think to myself what if I don't like how I look...then I glance up at the clock. 5 minutes. I have this feeling of extreme sadness, no dread though(not until I woke up).
Then I see this guy I used to know(in life) and ask him how he died. Then I see this girl I don't like in real life and we talk very nicely to each other and then everything disappears.

I wake up and my eyes are wet from crying.

I'm TOTALLY freaked out! What does this mean? Are there afterlives? Cause I always thought that when someone dies....they die. Does this mean I'm going to die??!

Can someone tell me what this means! I can't find any "Afterlife" keyword in any of the dream dictionary things.
It seemed so real. I could tell it was a dream. But there is something about it that makes me nervous

To see the dead in your dream, forewarns that you are being influenced by negative people and are hanging around the wrong crowd. This dream may also be a way for you to resolve your feelings with those who have passed on. Alternatively, the dream symbolizes material loss. If you dream of a person who has died a long time ago, then it suggests that a current situation or relationship in you life resembles the quality of that deceased person. The dream may depict how you need to let this situation or relationship die and end it.

To see and talk with your dead parents in your dreams, represent your fears of losing them or your way of coping with the loss. You are using your dream as a last opportunity to say your final good-byes to them.

To see your dead sibling, relative, or friend in your dream, indicates that you miss them and are trying to relive your old experiences you had with them. In trying to keep up with the pace of your daily waking life, you dreams may serve as your only outlet in coping and coming to terms with the loss of a loved one.
