It's a fine and daring movie to make but the makers could have given the viewer a little more help. Tilda gave a great performance. I'm pretty sure we are witnessing Jessica's dreams and her memories in the first half of the film rather than real time events. Since they are not in chronological order so it can be confusing to the viewer. Also, unbeknownest to her, I believe Jessica has telepathic power for receiving other peoples transmissions. She is receiving signals from another person, who she later will meet in the last third of the film, who is transmitting some of his memory and ideas to her and causing her to imagine scenes and a person that is not real. Some of this is cleared up in the last third with that surprise finish.
The older Hernan is a powerful outer space alien in the form of an older male human. He placed on earth and was born and raised on earth. He has special powers to remember all events of his life, to pick up past experiences of strangers from material objects, he also can "die" for awhile and regain life as he does in the film. When in close contact with Jessica she receives his alien memories very vividly.
The young Hernan was the older Hernan contacting her in a dream to help her reach him. The older Hernan memories are the source of the boom sounds she has been hearing. They were caused by Hernan's spaceship leaving earth and leaving him behind. Jessica's sister has died. Jessica signed the death certificate and other papers. We see Juan and her and the child leaving the home in the rain without the sister. The dinner scene is an event that occurred before the dentist Andres died and before the sister got very sick. But present day day Jessica is seated at the table in her dream so she is confused.
Maybe the point of the film is to speculate that some of our own memories may be distorted and that we each may be receiving ideas from a supernatural source without being aware.
