OH! For your first idea—go watch Lilou for inspiration—not exactly the same thing but there're similarities.

I love the second idea!!! The alien looks adorable!!!

First of all—love the art—I'm getting Temmie vibes—and, maybe some NOBEL vibes as well? But, ohhhhyeeeaaah—I'm a huge fan of your ideas. I've always loved characters that can read people's thoughts or see some aspect of their mind, so the fact that they're able to view people's dreams? Lovely. Is she able to control this ability? Or, is it involuntary, like any of the other senses, and she's forced to see everyone's dreams at any time? Does she see them as if they're coming out of a thought bubble, like depicted in the drawing? Then, friendly neighborhood alien? Postal worker? MMMMMMMMM. A marriage of ideas that I approve of wholeheartedly. Is the alien well-known within her neighborhood? Does she live on Earth? Another planet? Does she have other alien neighbors? Or, is she the only one? Lastly—office lady (I presume)? Magical creatures? Mhmmhmhmhmhm. *Rapid nodding* Oh yes. Are other people able to see the magical creatures? Are magical creatures common knowledge? How do people react to her use of magical creatures? Or, does nobody ever see it?
