Dreams
TheBramble:
Some of the latest theories on sleep see the REM period and dreaming as a time where we can release unexpressed emotions arising from our actions and thought from the previous day.
So for example if you had a blazing row with your wife before going to sleep BUT got everything off your chest, you would probably have a sound dreamless nights sleep.
However when trading we're confronted with so many emotions that cannot always be expressed. As such we might get overloaded and our brain needs to release or act out the emotions during sleep in a dream.
Sleeping lots doesn't necessarily mean you are depressed, but its a similar process. Depressed people often have negative ruminations and go over negative events and thoughts in their head, creating unexpressed emotions. Depressed people often sleep a significant amount and wake up feeling shattered, because there's too much for the brain to deal with during sleep.
Basically as you've said, it's your brains way of sorting itself out. Having a more balanced life. As already suggested, leading a more balanced life is the best solution. The right "balance" depends on our own personality type.
"stress" is defined as being in a situation where that exceeds your ability or perceived ability to cope. This is different to the obvious excitement of feeling in control leading to the almost zen like state of 'flow' where you feel totally in control of the situation.
When it comes to anxiety there a few steps you can take. Albert Ellis has written some good stuff on this topic. He talks about there being 12 common irrational thoughts that lead to anxiety and unhappiness.
Basically we're usually guilty of the following:
1. ignoring the positive,
2. exaggerating the negative, and
3. overgeneralizing.
Some of the 12 most relevant to trading are:
5. The idea that if something is or may be dangerous or fearsome we should be terribly upset and endlessly obsess about it -- instead of the idea that one would better frankly face it and render it non-dangerous and, when that is not possible, accept the inevitable.
6. The idea that it is easier to avoid than to face life difficulties and self-responsibilities -- instead of the idea that the so-called easy way is usually much harder in the long run.
8. The idea that we should be thoroughly competent, intelligent, and achieving in all possible respects -- instead of the idea that we would better do rather than always need to do well and accept ourself as a quite imperfect creature, who has general human limitations and specific fallibilities.
9. The idea that because something once strongly affected our life, it should indefinitely affect it -- instead of the idea that we can learn from our past experiences but not be overly-attached to or prejudiced by them.
10. The idea that we must have certain and perfect control over things -- instead of the idea that the world is full of probability and chance and that we can still enjoy life despite this.
