Death of a Loved One

This isn't a usual post regarding girly period stuff, this is something that's personal. A year ago I lost my cousin, he and I were close, felt like a brother to me. I've had 2 dreams about him where I would somehow meet up with him on my way somewhere and exchange "I miss you" and I haven't dreamt about him since. Do you think he visited me in my sleep?  & have you ever dreamt about a deceased loved one?
