So I was asked about this in another post in chat so and I'm to Lazy to make a summary myself. In arc 4 of the story Subaru gets shown what happens after his deaths he has had. This contains spoilers from arc 3 as well.
The deaths he sees are: Note that in arc 3 he dies 5 times in LN and 6 in the WN His first death His Suicide off a cliff His 2nd death in arc 3 (Last one in Episode 15) His 4th death in arc 3 (this in the WN but not LN) His 5th to last death in arc 3 (4th in LN) His last death in arc 3

Forced into starting the second trial, which was seeing the continuation of his 13th death(12th for LN), the time he killed himself after seeing that Rem's name and memories were eaten. Wilhelm and Ferris tried to save him, however the thing inside of Subaru tried to attack them, causing Pack to freeze the entire area. At that moment, Subaru returned to the grave, but soon after he was pulled back to the trial, this time to view his 12th death(11th in LN), the time Ferris and Julius had killed him along with Betelgeuse. He watched as everyone there grieved for him, with Julius stating that he had wanted to be friends with him. He was forced back to reality with his words, and after realizing that the voice that started the second trial was his own voice, he was forced to watch the continuation of another death, this time his 7th death where he had jumped off of a cliff in front of Ram and Beatrice. Standing next to his dead body, an angry Ram tried to lash out at Beatrice but stopped when she saw that she was crying while kneeling next to his body. Following that scene, he was forced to view the continuation of his 9th death, the time when Pack had frozen him at the Roswaal Mansion after escaping from Betelgeuse's cave. Reinhard had confronted Pack after Subaru's death and killed him, but not before Pack mentioned that Reinhard could only become a hero. Once he had killed him, Reinhard commented that Felt would be sad.
Afterwards, he was forced to view his 1st death, the time where Elsa had killed both him and Emilia at night at the Stolen Goods Warehouse. Once Elsa had killed both of them, Pack appeared to take revenge, freezing the entire area. The trial moved on to Subaru's 5th death, which was the time he was killed by Rem as he tried to make his way to Emilia's room. After hearing that Rem had killed Subaru, Emilia cut ties with Roswaal, slapping him when he called her actions a tantrum. She then had Rem guide her to his dead body as she had decided to bury him in Elior Forest. The trial moved on to Subaru's 11th death(this death doesn't happen in the LN), which was the time he was forced to kill himself after being controlled by Betelgeuse. Emilia had come down to the village when the female Betelgeuse was there, forcing Beatrice to send her back to the mansion and Pack to break the contract and freeze Betelgeuse's soul. Once he viewed the scene, he returned to a place he didn't recognize.
