Another dream with spirit return...

Morning! Can anyone shed some light on this please. Part of one of my dreams last night was going swimming with my therapist, andrew(partner) was there also, and i think my mum. We were initially looking around this ancient/historical ship (dream night before was in same place but boat was newer and was in sea at times), my therapist was smiling at me quite alot, and then it turned out there was a swiming pool inside one part of it which we were admiring. Then after looking at time, wondering if there was enough of it, we decided to have a swim (Even my therapist had her S>cotume on, although she didnt swim much). The pool was in like a shell shape with pillars/structure in middle, then as my view spanned, it then went down into a lower section and looked more like a modern little pool. I was in this little pool (think therapist was watching me from balcony part, higher up) facing the other pool that was contained up higher, and before i knew it my Grandad (who's in spiritworld) dived in,his face was clear as day nder the water, and he needed my assistance to help him back up to resurface which i automatically did. Someone else was in pool at the time but dont know if it was my mum (grandads daughter) or my partner andrew?

Anyway, alot of my long dream last night was like a follow on from the dream the night bafore, and there were lots of competitions going on off the ship. whereas thgenight b4 they were being prepped on the ship, but played out off the ship.
And in the night befores dream, a girl i used to know from school who was in running race turned into a manequin and my mum was trying to sell her to a lady on a stall which was like clairvoyant but not. plus i was a part of a family with lots of other girls , which in real life im not.

What is strange about last nights is the fact that my grandad just popped out of the blue- his eyes wide open, then once he surfaced, he was gone again.???? suggestions?
