Actually, as far as I know. There are essential differences.
Dreams at night take a long time to brew, so you have enough time for your subconscious to sort out what you have seen and heard these days and arrange and deal with the problems you are facing. Therefore, you usually have quality dreams in the early hours of the morning or when you wake up from sleep. In this way, your subconscious mind will tell you the dream after thorough sorting and reasoning.
And daytime dreams, such as taking a nap, take a nap, have short time and insufficient preparation time, and are often just cranky thinking activities, which can't solve inner confusion.
So it can be seen that dreams at night are more enlightening, while dreams during the day are chaotic and have no profound significance. Of course, I don't deny that I have meaningful dreams during the day, which is much less than at night. )
