Dream of number

I am on a field trip with my students and the last night it is time for bed but I say "wait, I have a little gift for each of you students". This means they have to wait for me to get my gifts ready. I return to my room and start to gather the little gifts and it takes a long time. I return to big room where we are to meet and I give out gifts but the whole process is much slower than I thought and much of the dream is about me trying to find the right number of souvenir gifts from my bags, my closet, my shelves and even outside in trash. I can only find about half as many gifts as I need and no one says thank you and it is getting confusing. Childlren are ready for bed but I am not through looking for more little gifts to give a way. I am aware that it is too late to be doing this.
