Dream About Getting Picked Up From School

I dreamt that I was getting picked up after school (I graduated in real life) and I was looking for buses but at the same time my parents were both there to pick me up and I was with them on the phone. I went inside a bus and they were handing out tacos and they looked really good but I was only thinking about how it would make me gain weight. I ate two but I felt bad about it the whole time and I regretted it right after. Then I went on a bus home and then realized my parents had gone there to pick me up and I felt bad so I called them and said that I forgot they were there and that I took the bus. I got off at my old middle school and I called my parents to tell them to pick me up from there
