What Happened?

Well I've had 2 lucid dreams that I can recall before, both within the last 4-5 months and about a month apart them both. I've only ever had a lucid dream sleeping in a different sleeping place, like on a different bed or at a different side of the bed from usual.

The first one I had is what I want to talk about, basically I was sleeping on a bed at someone else's house and it was the second time I had ever slept there on that bed. I woke up at about 6:30 AM or something so I went back to sleep after thinking about stuff like 'This world is really weird', 'What should I do if...' and stuff like 'Imagine a world without...' and then I got back to sleep. This is when I went lucid I believe and I started out on a beach and instantly started thinking 'How am I going to get home, where am I going to find the money to get home' as it looked like a place I used to live (different country) so I instantly thought I was there. Anyhow I got off the beach and there was some shops just on the beach front so I went inside one of them. After going inside I saw about 7-10 people inside looking around and buying stuff etc and I saw this man and I looked at his hair and then turned around and thought 'When I turn back around he won't have any hair' etc, so I turned back around and his hair was half bold and half there, after that I woke back up, I don't know what happened in it.

Anyone ever had a lucid dream like this? Or could anyone explain what happened to me? From what I know it was my first one and about 5 months after I found out about lucid dreaming and I always did reality checks every now and then but not regularly.
