Inferences: Probably Sunset since most people aren't awake to watch the sun rise. Also the sun is not visible. The water looks like some sort of river or lake winding down to the boardwalk.Or is it a bridge? The screaming person seems to be scared or frightened. The other people walking ahead don't seem to notice. They don't turn back and they continue walking. The island- like structure in the distance has a few tiny figures that appear like humans. Above them, there is a blue- ish tent. It also looks a little like a boat.
Interpretations: I like this painting because of all the colors. When Edward Munch painted this, I think he was trying to emphasize that the person was screaming and no one was paying much attention. Everyone else continued doing what they had been doing all along. I think this shows that not everyone will notice, or care, but you just have to get over it and continue walking down that boardwalk. I think the bright colors from the sky can represent the lighter issues, or the issues that aren't as huge as the darker (represented by the dark blue water) issues or problems in life.
