First Lucid Dream... interpretation help?

So I had an incredibly short Lucid dream :raised_hands: first one ever! I was swimming underwater and I realised I was underwater swimming and it was a dreamā€¦ could change direction. Then I said (in my head to myself) I wanted to go visit my ex now in my dreamā€¦ and waited a little while for it to materialiseā€¦ it didnā€™t. I woke up :joy: which was annoyingā€‹:rofl: I thought I was meant to be able to control a Lucid dream! I seemed to only have partial control - eg could swim knowing was dreaming but couldnā€™t change locations
