climbing up the hill with a guy (in real life he is not my boyfriend but i like him and i think he is not serious) holding hands. it got really hot and i started to moan i will get a sunburn, he takes the sunlotion and rubs over my skin... we get to the top of the hill, enter some castle or some premises, he starts touching me, it feels really good, we have sex, i realize we are in the water, i turn around and see myself in the mirror - naked...

any ideas?

Wish fulfillment?
