I know the alpha / Theta waves music can help us in visualization, but it can not listen more than 1 hour per day. May I know when should I listen these music? If I listen the theta music before go bed to sleep, will it affect my sleep can not go to the delta waves? how long does it affect?
If I listen before going to work, do I have difficultly on focusing?
Thank you Graysen, thanks for your explanation.
I still have some confusion, if I want to have a good visualization, I should listen Alpha music or theta music? And what time should I listen? I only have time when before go to sleep. But If I listen before sleep, I am afraid I will dream all night and can not get a deep sleep.
As I explained, there are different theories behind each level or wave - so there is nothing set in stone. So you could use either one. Most people feel drawn to one as their favourite to listen to and use. Like most LOA tools, its really depends on how you feel when using it. If you use theta, and feel good - then thats the one to use. If you use Alpha and feel good - then use that one. Some people are now saying that Gamma waves are more superior to both alpha and theta waves. Its really up to the person using it and how they feel.
Using prior to sleep is fine and there isn'y any need to worry. The only issue that I'm aware of is that most peple tend to put their theta/alpha tracks on repeat playing on their ipod and so that prevents them entering the deep sleep state (of delta and REM). But you can easily listen to prior to sleep without any ill effects. In fact, some people find it extremely beneficial because it puts both their mind and bodies in a relaxed state.
Many of the theories out there on the diferent wave lengths haven't really had research updated behind them so they are based on older factual information that was collected.
I listened the theta music these nights but I think I can't get in a deep sleep because I dreamed all night >.<
Well if you listened to theta prior to sleep - it often makes people have vivid dreams but doesn't stop them reaching sleep. If you were to listen to it on repeat - then that would. For most meditators, they are taught to not meditate immediately before bed, because it often induces deep relaxation but is a semi alert or aware state. So it may be true for you too based on what you say. Try listening to the theta waves sitting upright, and do something else immediately after and then lie down and try to sleep.
