Seeing or having a fit in a dream is usually an indication of releasing deep tensions often caused by fear or not being able to meet deep or powerful emotions or stress.
In life and sleep we have two powerful actions working in us. The first is our waking experience based on having a body, its limitations, vulnerabilities and a particular gender. Our second is the power that gives us life and continues to express as dreams, in our breathing and heartbeat – our life energy. This I have given the description as the Life Will.
While we sleep our conscious self is largely or totally unconscious, and while we dream our voluntary muscles are paralysed – therefore another will or motivating force moves our body. So we have a Conscious Will, and what I will call a Life Will. The first one we have experience of as we can move our arm or speak in everyday activities; but the second will takes over when we sleep. See Sleep Paralysis
This Life will can move us to speak, to move our body, and in fact do things that we cannot do with our Conscious Will. See LifeStream-People’s Experience of LifeStream- Life’s Little Secrets - Arm Circling Meditation
Example: For some considerable time now I have been troubled by a nightmarish dream which is so realistic sometimes I think I am going to die. In my dream, which sometimes comes within three quarters of an hour of falling asleep, I have swallowed something which is literally choking me or is going to poison me. I wake up and rush down the stairs to the kitchen spitting and choking, holding my throat and making all sorts of disturbing noises which frighten my wife. I have had this dream as many as five or six times a night. My doctor says it could be to do with the last war. I was a child then and my dad had to constantly wake me up to take us down to the shelter, sometimes as many as four times a night, and we were bombed out twice. I cannot recall having any fears about this at the time.
Here is a typical example of trauma trying to be released.
