Dream 1

When I was in bed either before I went to sleep or after I woke up briefly, I remembered part of a forgotten dream from the previous night, but I accidentally went back to sleep without voice recording it so I mostly forgot it again.

I think that the dream involved me moving around (maybe walking) past / by various options / choices, my dad was possibly in the dream at some point, but that is all that I can remember now of this dream.
