Violent dreams may predict illness in advance

Is it possible to retrieve those old memories? Can we force our brain to not forget a certain memory? Who is in charge of all this?

Jasmine, the Hippocampus of the brain is important for taking care of new memories.These memories are then transferred to the frontal cortex for long-term storage. However, for how long would this remain depends on the degree to which we are dependent on the hippocampus and frontal lobes for recallling that memory. Some tragic incident that has left a great impression on one's brain would be easy to be recalled by the frontal cortex (since you have been recalling that incident a number of times. In other words, you intentionally or unintentionally did not want to forget that incident). So whether you would be able to recall a particular old memory depends on where the memory has been stored and how old that recollection is. If the recollection is new (the memory could be from your childhhood so it is old, but since you have been recalling it every now and then, the recollection would be new).

A two-year old cannot remember whatever happened to him/her in the second year of his life but a 22 years old can remember many events of his past, depending upno how strongly those events had left impressions on his brain. When the brain is puzzled to recall a given memory, the brain not only processes the question but also tries to recollect any associated information stored in it (memory retrieval). If the recalled memory has been associated with a personal event in the individual's life, it would be easier to recall it. Furthermore it also depends upon the time that has elapsed between the registering of the memory and the recalling of the memory. Although it is easier for the brain to recall recent events than older ones, our old memories of the distant past could remain as rich as the recent ones.

Who is in charge? The hippocampus of the brain stores recent memories. For long-term storage of memories, the hippocampus transfer these memories to the frontal cortex from where they could be recalled. The frontal cortex is evolved to be more complex with a wide scattering of neuronal connections.That is why neuroscientists believe that long-term memory storage should occur in the cortex. The latter view comes from studies on the amnesic patients who were unable to recall memories from distant past but were unable to recall the recent ones. Lesions in the Hippocampus region could be seen in these patients.

what if you have these types of dreams and then it stops all of a sudden?

DZJ, the violent dreams in question have been observed in cases of patients with neurodegenerative disorders. A healthy human seldom see violent dreams with disrupted muscle atonia (sleep paralysis which is commonly known as "KHAPASSA" in Pashto) on regular basis. Some healthy humans experience regular episodes of KHAPASSA, other would experience once in a blue moon. Stress, sleep-deprivation, sleeping in upward sleeping position, anxiety, depression, hormonal changes are the possible causes. Changes in lifestyle and sleep habits could decrease the frequency of violent dreams. Personally, I have experienced violent dreams for an entire week when I was preparing for this one BIG exam and I took it as a life and death issue. I never had violent dream after appearing in that exam since I removed the "exam stress" from my mind, forever.Oh, actually all forms of violent stress..Khapassa is just too difficult to handle at night, lol.
