I keep having vivid dreams.

Last night I was at a friend's wedding, but instead of a reception they went on a pub crawl. For some reason when we got to the hotel I got really confused and when I got to my room everyone was already sat in my room and then when I went to the toilet and came back out they had already left.
So I texted my friends to find where they'd gone but it was an old phone, I couldn't remember where my real phone was. I bumped into an old friend on the way (well, FWB friend) and he told me to text me where I was later. I then got to the pub my friends were in, it was a mix of old friends who don't actually know each other but they were all together.
I went to the bar to get a drink and it was empty but all the barmen just looked through me, but then finally I ordered a pint of Guinness. Suddenly this man was next to me and he looked mid 20's and started flirting with me and I was really confused because noone ever flirts with me and so I felt like I was waiting for the 'joke' to fall like his friends to come over and laugh or my friends to come up and give him money for flirting with me like they bet him he wouldn't be able to stomach it. We were talking for ages & I still had no drink so I asked the barman where my drink was & he was like 'you didn't order one' but I did, so I ordered again and the man went to get a coke and I could see an ID card and it had his DOB as 2006 and I knew that that made him really young but couldn't work out how young.
The barman finally put a drink infront of me but it was a pitcher of lager & I was like 'I didn't order this' and he said 'I know but we ran out of Guinness so we're only charging you the price of a pint for this pitcher' so then I paid and realised I had hardly any money & no bank card so I thought I'd best get more money because we'd only just started drinking and I decided to phone my parents to ask them if they could bring me some money (which made sense at the time for some reason), but I couldn't work out how to use the phone.
All my friends were really nasty to me and kept treating me like I was a complete idiot and ruining everything so I decided to leave because they were talking about all of the nightclubs they were heading for and none of them offered to lend me money when I explained I'd forgotten my bank card, but when I walked outside it was about 8am. I knew I didn't have enough money for a taxi but I didn't know where I was so I just started walking and hoped I'd see my hotel. I walked for what felt like hours, then suddenly, just as I saw my hotel in the distance, a child appeared driving a massive pink tractor and told me she was my cousin and had been sent to take me to my hotel. But then she reversed the tractor into a lorry behind her. She only looked about 9 or 10 and I didn't understand why she was driving it but I knew I didn't know how to drive it myself so I couldn't help.
I'm not sure what happened then but I was back to walking and arrived at my hotel but I couldn't remember my room number and couldn't find my key (this is a recurring theme in my dreams).
I tried using the old mobile again but all I could get was people's bedside alarm clocks saying what time it was.

I've had a few night out/nightclub dreams the last couple of weeks which is strange since I've not been on a night out in years.

But yes, anyone any insight?
