I quiet a couple of things which is awesome.
- Thunderstorms/Lightning. It makes me calm no matter where.
- Light rain/Rain whilst inside my room. It like it when it is lightly raining on me or just plain raining when I am in my cosy warm room.
- Warm soft summers wing. Just feeling a warm breeze is nice.
- Classical Music. Depends which though.
- Anime theme music. Few exceptions.
- Being on my bed. Just thinking.
- Looking outside my room window.
Its nice listening to these things even when I am already relaxed.

My top one has to be the summer soft breeze...it just feels so nice especially in a hot Australian summer.
