I do not have a happy place that I imagine. Though there are lots of things that make me happy, and one of them could be considered a "happy place" type thing. I reminisce. I think of a happy time(s) in my life. It helps to journal it out. On that note, some types of journaling make me really happy. Like gratitude journaling.
Sometimes when I meditate, I imagine the ocean. Maybe the ocean is my happy place. It certainly is a wonderful place.
Your class sounds really cool, Ohmydaisy!
