Deb you are the only one who knows if you are stress or not every body has different stress levels...your life sounds normal to me...lol....but maybe it isn't for you...The heart attack part does not change the dream ..He is not going to die ...the only other way to look at it is ..If he die it would solve some of your problems in your mind and you really are not wishing that Your mind is just picking up small bites here and there and coming up with the dream....If it would make you feel better have him have a check up at the doctors and ask them to check his heart...If you are continuing to dream the dream ...Tell yourself before you go to sleep to NOT dream that dream..If you should as soon as it starts wake yourself up and say I do not want to dream that dream..Your mind will pick up on not continuing this if you tell it not too enough times...Be positive with what you say about not dreaming it...the mind will pick the positive....Do not give it a choice of any kind ..Just a straight DO NOT dream this then that is the only choice it has connected to this dream and will pick up to stop the dream....
