I initially wrote this on youtube and was re-directed here to discuss. I am just going to copy and paste the original comment to get some advice.

i watched this and made notes yesterday. I am off work at the minute so trying to fit in all the exercises is not an issue yet and so i have had time to take time on it. I spent a long time staring into a candle flame and just breathing and watching the colours change and it move. Maybe i spent too long, as i kind of almost drifted off and seen figures dancing almost. Like when clouds look like animals, not sure if i should have been concentrating more. I am unsure what i should be concentrating on to prevent my mind wandering in this way and forming shapes into forms. just imagining other things i guess my mind gets bored easily if i dont keep it busy. It always did wander and i would be in a world of my own easily - so any advice on this i would appreciate it.
