Yes, in the movie Joker, Arthur Fleck (Joaquin Phoenix) imagines his entire romantic relationship with his neighbor, Sophie Dumond (Zazie Beetz); the film reveals this to be a fantasy, though the later sequel, Joker: Folie à Deux, shows his actual interactions with Lee (Harley Quinn) as real, not imagined, despite fan speculation.
Arthur experiences a romantic feeling towards his neighbour Sophie, but later the film reveals that he was actually imagining all of their dates.
With Arthur suffering from mental illness, one of the biggest twists in the story was the reveal that some of what's been on-screen is only in Arthur's head, including his romance with Sophie.
In the first half of Joker: Folie a Deux, it seems possible that Harley or Lee could be a figment of Arthur's imagination as no other character acknowledges her, and she appears to move freely in the asylum. However, later events confirm that Lee is accurate.
We see Arthur fluctuate between what appears to be sadness and laughter throughout the movie, which can be confusing for viewers. Some identify his condition as Pseudobulbar affect (PBA).
The bathroom dance in Joker wasn't in the script, but it ended up defining the movie. An improvised moment became the axis around which Arthur Fleck's transformation spun, reshaping both the narrative and the cultural afterlife of the film.
He lived with his mother Penny Fleck, who had possibly adopted him. Enduring his abuse, Arthur was found tied to a radiator, bruised and malnourished; he suffered severe head trauma that was believed to have caused him to have his uncontrollable fits of laughter.
In their last encounter, Arthur attempts to convince Lee to leave with him someplace. However, Lee simply rejects Arthur and abandons him. This implies that she was never in love with Arthur himself, only his Joker persona.
But behind him, the true Joker is revealed, as the young man cuts a bloody grin into his cheeks. Yes, this means Arthur was never really Joker in the first place; he merely served as the inspiration for the man who'd become Joker after him.
The Tick explains that he believes Arthur to be a hero and wants him to join him in fighting crime. With Arthur's brain and The Tick's brawn, they could be an effective duo. The Tick gives Arthur a winged supersuit that he procured from Miss Lint's warehouse when he shut down the operation the previous night.

Joker Jr. was born after The Joker, who had manipulated Harley Quinn into re-entering a life of crime, impregnated her without her knowing. Harley out of shame refused to accept the child and gave him up. He grew up being transferred from various orphanages and foster homes to people who never loved him.
While she cares about her son, she has shown to lie to him multiple occasions which leads to her death. Despite seemingly being kind to Arthur, it later transpires that she gossiped behind his back and scoffed at his idea of being a comedian and his notion that he was in the world to bring joy and laughter.
I think the fridge scene represents a temporary escape from the world. It's a place where he can just shut himself out and feel numb. On the other hand, it could also represent stepping into a world that is also cold, dark, and suffocating...
Director Todd Phillips insists he won't be making Joker 3, and that Joker: Folie A Deux will bring his take on the story to an end. Director Todd Phillips is back on the promotional trail, as the release date looms for his high-profile sequel, Joker: Folie A Deux.
Despite both characters being hyped up as super crazy, neither is usually portrayed as all that crazy. They're both pretty aware of the world around them and their own actions. That being said The Joker is usually calculating and willfully malevolent, where Harley acts out of a genuinely twisted understanding of love.
JOKER'S LAUGHING DISEASE...
Arthur Fleck clearly had a diagnosis of pseudobulbar affect—uncontrollable episodes of crying and laughing, made worse by any emotional content. In the US alone, 1.5-2 million people suffer from this condition. During his laughter, there was always a deep sorrow and agony underneath.
In reality, Lee went to grad school for psychiatry, lives with her wealthy parents, and chose to have herself committed so she could meet "Joker." Arthur eventually confronts her and she claims to be pregnant; however, when that's brought up again later, all signs point to it being yet another lie from Lee.
Once he reached safety, he sent a goon to Harley to apologize, exploding to make the point. Still feeling betrayed, Harley redid her outfit (which the Joker initially appreciated) and returned to the Joker again to break up with him, claiming that he mistreated her and never loved her.

Before the Joker killed Gambol, he stated that his father, who was, according to him, "a drinker and a fiend", had, in the past, attacked his wife, attempted to defend herself with a kitchen knife, but he took it from her and then sadistically attacked her with it before he sliced his son's cheeks into a Glasgow Smile, ...
