Dreamt Of Old High School Hotel Reception Encounter With Old Classmates

This dream was about

I had a dream I was in my old high school studying, I come to reception and it was turned into a hotel/education center and my old classmates worked there but they all dyed their hair and got older so I didn’t recognise most properly but i knew I did know them. I talked to most and was friendly, I asked one of them if I could put my shoes and bag under the table whilst I wait for my mum to pick me up
