Yume Tsushin has two endings, one taking place in dream world, and the other in the real world. Both can be seen after collecting all of the game’s Effects.
Spoilers:
This ending is achieved by collecting all of the effects and afterwards using the telephone in the Nexus. While using the phone, the camera will cut to a small view of a pink room with a ringing telephone, possibly implying that Wormiko is trying to call an unknown person. After a couple seconds, the credits will appear.

This ending, in contrast to the first one, takes place in the real world while still requiring the player to have all of the effects.
Instead of going to sleep, go outside of your apartment and go to the nearby phone booth. Enter the booth from the top and interact with the phone. Wormiko will then sit down as the credits appear and the ending music plays.
The real world version of the Hat and Scarf effect can be equipped for this ending, however it doesn’t change much aside from Wormiko wearing it during the sequence.

“Tsūshin” (つうしん) in Japanese can mean either:
Both of those meanings could be seen in both of the endings, communication especially is prevalent.
It seems like the main character is trying to communicate with somebody who is likely important to them, perhaps even being anxious about them/their relationship with each other.
