The way you say it makes it sound like you can just release a pressure valve and be done with it.

I think subconscious emotions are rarely ever "trapped" exactly. Pay attention to your daily life I am sure they will be out of there traps. For example maybe you get angry or afraid in certain situations, but you do not understand why. This would be a good place for you to start I think. Your subconscious emotions will certainly affect you in some way. You should try to recognize them when they do. Gadgets are fancy, but I think we are born with everything we need for our own wellbeing.

My vague answer for a vague question is: identification and understanding

Also I agree with what fisk_82 suggested. I am not sure what you mean by "release" though. I don't think dreams will free you from most emotional burdens, but at least you can see what shows up in your dreams and then deal with it from there.

It is not easy to release all the stress...hidden inside your mind. Your sub conscious mind is where your conscience stays. Meditation elevates your conscience level. So, practice meditation my friend.

I think emotions are always in the conscious mind. you can have unordered senses in sub-conscious mind; but not emotions. emotions take form out of those senses - conscious about some, unaware of the rest.

and, why feel that emotions are trapped? they keep flowing all the time. others may not notice it. but, you can feel. can't you? yes, if you mean that you want to make a show of it, then write a script, imagining the future circumstances; memorize it, and then act it when the time comes. well, I've seen Capris and Virgos are good at it.

Elgina,

meditation is for restoration. you restore a scattered mind through meditation. emotional outbursts need nothing but just a little bit of expertise in acting.
