Level 14 problem

[SwedKnoT]

I just passed a glass thing with fishes in it (don´t know the english word, haha)
When I enter the mind of a person, I walk into a toilet, water flushes in, I get out of there, hearing a guy talk in a mic/radio or something.
Where am I supposed to walk?
If i climb into the glass thing, I fail, and if I walk to long in the other direction, I fail too.

Thankful for help
