Some of her poems became songs, which became popular in Bulgaria in the 1980s: Зимна ваканция (Winter holidays), Пролет (Spring), Доброта (Kindness), Лунапарк (Fun-fair), Нощ над града (Night over the city).

Although she earned fame at a very young age, which defines her as "the youngest of the big Bulgarian artists", she did not have friends.

During the shooting of the film in Samokov, at night, in the disco in the resort Borovets, Petya met a Swedish man named Per, whom she fell in love with.

In her diary, she describes him as „далечния, светлия, чаровния, нежния“ (the further, the light, the charismatic and the gentle one).

They corresponded through letters for a period, but he would abruptly stop writing to her, which had deeply upset Dubarova.

It is evidenced from her diary entries during her last year of life that Dubarova's thoughts were consumed by despair and a sense of disappointment in humanity.

The most popular one is that The Young Communist League organized regularly "voluntary" work in a beer factory.

She left a note that says: "Измамена (Deceived) Младост (Youth) Прошка (Forgiveness) Сън (Sleep) Спомен (Memory) Зад стените на голямата къща (Behind the walls of the big house)

According to her English teacher, the day after her funeral, Petya's school woke up to walls covered in graffiti such as "Mamka vi!"

[3] The local poet Veselin Andreev partially accuses the teachers as well, by quoting Dubarova's mother's words at the funeral: "They killed my child!".
