Let's talk about physiological knowledge first. We will remember dreams, because we will be awakened when we dream. At that time, when we wake up, we will think of our dreams, so we will feel that we have had many dreams. We have four or five dreams every night. We don't remember them because we didn't wake up after the dream, so we don't remember them. And the place where you live is noisy, so it is normal for you to have many dreams.
The problem with this kind of love is that your dream is protecting your sleep, because you just had a horrible dream and your consciousness is protecting your sleep, so you immediately changed to a dream that makes you feel more relaxed and let you continue to sleep. This is a physiological mechanism of our self-protection.
There are many possibilities for your dream about the book of life and death. Let me talk about my feelings first: one possibility is that you feel reborn because you know that you love your family and say goodbye to the past. But you haven't figured out a way to convey this message to them (so I ran out desperately to call my family and tell them I love them, but the phone still couldn't get through)
Another possibility is that something has happened to you recently, which makes you feel sad, so you have a psychological feeling of where you will go. You may feel this way because you saw something in real life, or heard a story from a friend, which suddenly made you feel this way. But because you suppressed this feeling during the day, it broke out in your dream at night and made you deeply feel it.
Dreams are not real things, but the feelings in dreams are really real. The feeling in your dream is where you are going, trying to communicate with your family. This is the truest feeling in your dream. My suggestion: communicate with your family more. Love doesn't have to be expressed, but it needs to be revealed and cared for in real life. So I won't really leave myself regrets on that last day. As for whether there is a hint, as far as I am concerned, there should be no. If I am really worried about going to the hospital for a routine physical examination, I can do it. Let's focus on emotions, because in your dream, your phone can't get through, which means you can't communicate with them well. That's what you really need to pay attention to.
