Good Day Shan,
I would say all is well with your BrainEv experience. The thing is, everyone is different: different brains, different 'baggage' we carry around, different space we occupy i.e. stress levels etc. So expect a very personal BrainEv experience.
Why do I think all is well with you?
Dozing off. Par for the course - it happens to almost all of us. At the beginning of each level the brain is pushed (just like a muscle), and a typical reaction of this pushing is falling asleep. You will find, as your brain acclimatises, that you will spend more time awake. Give yourself time.
Tips for staying awake: Sit up. Change the time of day when you do your session (are you tired/worn out when you do it, say after work?)
You are getting increasing amounts of low alpha, some theta and even a bit of delta..... these frequencies are very relaxing, and we use them spontaneously when we want to go to sleep. Your brain will recognise these frequencies and may tend to doze off.
Mind straying off all over the place.
Par for the course, Shan. Look through the forum, most of us experience this. Monkey mind, brain chatter, beta-buzz, beta-frazzle..... While we may aspire to having a CALM mind, total CLARITY, clear FOCUS, not many of us out there actually manage this. Currently my life has at least two challenges which are totally out of my personal control (= fertile ground for anxiety and endless streams of thought); I have a few issues (baggage) I seem wedded to despite a desire on many levels to let them go (= more fuel for the monkey mind); and I am not an experienced meditator (= so I don't have an array of steadfast techniques to quiet the mind wherever I am, whatever is happening). Again, I am not alone. If you look around the forum, you will find others who hope BrainEv will assist them in boosting their brain's potential.
I suggest you use the 30 minute of BrainEv to let go. Really relax and let go. Just let whatever happens, happen. You may need to relax a little even before starting the session, just so you start entraining as soon as you hit the start button. When you stop controlling, self-monitoring, wanting this or than, expecting a specific outcome and truly LET GO, amazing things happen.
Have a thrilling journey - but accept whatever you get! Happy BrainEv adventure, Pure Bliss
