Sudden death of a person leaves and unexpected hole in the lives of others.
Aspects of life that are planned and expected that involve the other appear broken. Behaviours, once normal and routine, now seem out of place. (I still put the scraps down for the dog sometimes and it is years since she died) Communication begins and you realize they are not there to receive it.
They are no longer physically here but sometimes you can become aware of them and some people feel they are still in communication with the person who has gone from the physical realm.
They are in another level of experience and it is perhaps very peaceful and beautiful. You are still here with an absence of things that regularly took place.
Feel the absence. It is there. But also decide that you are going to create other things in your life.
Soon you will begin to do so and the hole will be gone and only the pleasant memories remain.
