Afternoon (3)

Context
Afternoon (3) was uploaded on July 29, 2020 by Hollis Coogan and has a runtime of 0:43. The description reads:

"This video I filmed in the afternoon. Through the door, it looked nice. It always does but this time especially, so I thought it deserved its own video. It's hard sometimes. I get blue, then I get red. I tried to communicate that feeling in one video. And some other things. I know nobody is watching. It makes me sad sometimes, it would be better if someone did. Then they would know what's happening, and they could try to help. I don't want anyone to talk to me it's more about how they talk to each other and what they talk about.

It's really beautiful out there. Why can't I just go out there? Well, I did yesterday."

Content
The entire video consists of a single door, presumably the door to the Garage. A serious of symbols flash periodically on the door as the video progresses while an ominous piano track plays in the background. During last 10 seconds (roughly) of the entry an misshapen apparition appears behind the door and bobs back and forth until the video comes to an abrupt end.

Analysis
The three symbols that appear during the video are as follows:


 * 0:09 - A blue tear drop
 * 0:20 - A red tear drop
 * 0:32 - A red tear drop with yellow lines angling towards its tip

All 3 symbols appear in the middle window pane, and a few seconds after the third symbol disappears the apparition then makes its appearance. The apparition is vaguely humanoid in shape (albeit with highly distorted features), but it is unknown who or what it may be exactly.

The meaning behind the symbols is ambiguous. The description does directly reference the colors red and blue, and these colors are also prominently featured in the previous two entries.
