I think the nature of dreams is the images, thoughts, and emotions we have about something we are scared of, wish for, want of, and desire. To some extent, I do believe in coincidence. I think that there are some events and situations that happen without a connection or explanation. However, I do believe that some events happen for a reason and are connected (Do I understand that at the moment? The answer is no). Memory is like a dream because both are a recollection of events, thoughts, images, and emotions. However, I think memories become cloudy over time and we mix them up with other memories. One can also think that dreams are bad memories in a blender. The images above are there for one's interpretation.
