Great choice of nickname and avatar.

Regarding the nightmares, there has been found some correlation between increased emotional states in waking life and in dreams (there was even a study posted by one of our members regading that - can't find the link atm). So, in general there might be a bit more emotionally laden contents if you are more emotional during the day. I'd say it's a good opportunity to catch some lucid dreams by reminding yourself about this and about becoming lucid next time it happens.
