I try to limit myself to responding to question about 12 volt electrical and Freightliner chassis , two areas where I can claim a certain level of experience .
Now dreams , I rarely have them but when I do , I can usually relate them to daytime stress . Sounds like you're somehow feeling helpless to deal with daytime happenings so your mind is still trying to wind down but just making the situation worse .
If you're watching too much TV ; news in particular ; cut back , and don't watch it late at night .
Find a quiet spot to go for a long walk , to make sure, your going to bed tired .
Read a book before bed , even if it's just a pictorial ( travel type ) with captions about south sea islands ; anything calming .
