The teacher 'high'

I am a fairly new teacher and last week I experienced something new. Maybe something athletes may call the runners high.

I was scribbling something on the board then this weird sensation came over me. I suddenly realised I am the teacher ,in a full classroom , students waiting for guidance , looking up to me and waiting to see what I was writing. I stopped mid sentence , smiled to myself and faced the eager waiting students and my heart warmed at this feeling and sensation. It's like the happy hormone coursed through my body and my vision felt a little blurry , sound in the background and felt like at an out of body experience.

Anyone ever experience this?
