I wanted to understand the purpose of the dreams. I feel like it seems to detract from the main plot (like in many other games here with dreams) and I'm personally more interested in what's happening to the characters in real life rather than the dreams.
Most dreams are based on routes, if you show more interest on Joan or Mrs. Smith you get a dream with one of them...
They don't detract from the main plot at all, they deepen it ,and bring more questions about the main story.
Just like real dreams they can relate to what the MC is living, or they can be the most ambiguous thing ever.
The MC's desires are portrayed in his dreams, things in the back of his mind also come to light in his dreams; like Eleonor.
They also serve to bring an introduction to lewd scenes with the MC's love interest.
This is not a harem game, you get to pick a woman per route, and that is also reflected in the MC's dreams.
I find your question/complaint very weird... Cringy actually.
Dreams are here to stay, they will bring more lewd content. They will also reflect the MC's past, fears, desires, and hopes.
Dreams are going to be a collection of short stories attached to the main plot, adding to the game's content value.
