Lucid mini dream help

Date: 5/17/2017

Didn't last long because I got too excited again! I was talking to my dad and couldn't work out what was different. Then I realised that he had aged 20 years and was wearing a funny hat. I realised I was dreaming and then it gradually faded away as I tried to hang onto the dream, and I woke up:( anyone got any tips to stay awake?
