Dream About Losing Dorm Key On Ship

I dreamt that I went back to college and I lost the key to my dorm room, but come to find out the dormitory was not a dormitory, but rather a ship. I emptied my purse, looking all through trying to find my key. Finally, I went to the resident assistant and asked if she could help me get a new key. She took me out to the dining area and I met the purser of the ship. he was very kind and told me he was the only person on the ship that handled all the keys. He issued me a new key and then showed me where my room was. He invited me for ice cream after I got myself settled. After I got myself settled into my room, I went back downstairs to the dining area. Everyone was sitting at tables eating ice cream, but the ice cream itself was just laid out on the tables without plates or bowls. Some of the people that I was with did not want to have ice cream that way. I decided I would go for it and I was able to find raspberry sorbet and birthday cake ice cream. It was pretty good. I wanted chocolate, but there was no chocolate available.
