Date: 2/22/2019

In this dream I was at my house in but it wasn't my house then my brother started making a water slide and then he threw up and I got scared because I hate throw up so I walked away trying to not look at it then suddenly I was in my moms bathroom and I threw up in the sink I honestly don't know why but then I saw my brother again and I said to him you made me sick if I see throw up I do the same then I walked away and I woke up
