Last night I dreamt a strange dream and have no idea of the meaning.

I was queuing to pay for a night spent in a caravan for ?100 with a friend (female) in front of me (friend similar to another friend but never seen this ones face before) we were acting like best friends. We were waiting there for a while when I said to my friend ''i'm paying by cash why dont you pay mine for me on your card and i'll give you cash, your paying by card anyway''. Next i'm in a supermarket with a male friend, there he got some beer, but the supermarket worker was a boy I went to school with and I had the feeling he wouldnt serve me acohol. So I had a bite of the female friends chocolate bar.
As we were walking back down hill (the first female friend and the male friend) I called the male friend by his name 'R' but the female friend said ''How can you call him that when R is dead call him by his name''. I replied by calling him 'C' (who is actually R's dad who died 2yrs ago but C was same age as R now) C said 'its ok'', then laughed then he ran down the hill waving his arms and laughing like he was a little child, back down to the caravan queue.

Does anyone know what this could mean?
