They have probably been doing a lot of crazy things that you think were dangerous and it is because of this that you feel like you need to talk to them and see how they are doing. This is definitely the reason why you are having such terrible dreams, because you are worried about them. Even if their behavior won’t actually result in death, it will result in a serious injury if you don’t pay enough attention to what’s going on and this is a good enough reason for you to make sure that you are paying close attention to your friends and your loved ones that might be in danger. Be responsible for them when they refuse to do so for themselves, they deserve it every once in a while.
Your love is the person that you spend all of your time with, the person you rely on, your best friend and companion in life and someone that you can always rely on in a pinch. This is a person whose happiness and livelihood you are very closely related to, to the point that when they suffer, you suffer and when they go through something tough, you are feeling it too. To have a dream in which you witness the death of a love it means that you feel like your relationship with the one you love is becoming less passionate or more conventional. You need to make sure that when you are awake you are doing the best you can to help keep your relationship together or else you won’t be able to function and you really need to be able to do that if you want to make any progress in your relationship or on your own outside of the relationship as an individual.
