Question 1

what is deja vu?

Accepted Answer

Deja vu: Deja vu is the sense that something which is actually unfamiliar, is familiar -- or has been experienced before.  Most people have had such experiences occasionally, but in more frequent occurrence it can be associated with temporal lobe epilepsy.  In them, it can happen just before a seizure. But, this experience does not have to mean any abnormal condition at all.

Question 2

what causes deja vu?

Accepted Answer

Déjà vu: French for 'already seen' is the sensation of having seen something/person/place before even though you know you haven't. Theories as to the cause abound [see following site for some: http://science.Howstuffworks.Com/science-vs-myth/extrasensory-perceptions/deja-vu.Htm] but no one knows for sure.

Question 3

why do we get goose bumps?

Accepted Answer

Hair follicle muscle: Each hair follicle has an attached erector pili muscle. Goose flesh occurs when those muscles contract, pulling the hair vertically and producing a small bump of muscle under the skin. Stimulators are cold and fear.

Question 4

possible causes of goosebumps on the head?

Accepted Answer

Goose bumps: Stimulation of Arrector pili muscles.

Question 5

how long does it take a goose egg to go away?

Accepted Answer

A few days: A hematoma, or "goose egg" is a swollen bruise under the skin following an injury. It can occur anywhere on the body but is often noticed on the scalp. If the lesion lasts longer than a couple of weeks, see your doctor to make sure it isn't something more serious.

Question 6

what are goosebumps /& what makes skin move like that?

Accepted Answer

Muscle contraction: Tiny, erector pilaris (?Sp) muscle for each hair follicle contracts making hair 'stand' up. Useful for thick fur covered animals to increase air cushion ; insulation. May have role (for them) before trauma so hair acts as intermediary (/lubricant if you will) to reduce transmission to tissue below. W/humans, not-so-much.

Question 7

what does it mean when a person gets chills and goosebumps when not cold?

Accepted Answer

Flight or Fight: As you've indicated "goose bumps" occur in response to cold as your body's way of generating heat.  But this reaction (piloerection) also occurs in response to strong emotion.  Fear for ex. Stimulates the sympathetic nervous system which causes the smooth muscle at the base of hair follicles to contract resulting in "goose bumps".  Rarely, goose bumps are associated with medical disorders.

Question 8

i was lying on my back, then got goosebumps suddenly followed by a pain in my chest. i'm 17.

Accepted Answer

Vagal reaction: I would wonder 'what' you were doing on your back that could have triggered this off?  Stimulation of the vagus nerve from a 'gas pain' could account for these symptoms since it could affect the autonomic nervous system (goose bumps) and bring in sensations of chest pain - since it is a long winding nerve and could bring in nerve signals from that region. Hopefully these symptoms were transient.

Question 9

it seems when i get anxious i feel deja vu. this goes away when i'm tired how do i get the deja vu to stop all the time?

Accepted Answer

Memory: Anxiety interferes with the retrieval of memories. One of the  hypotheses about what causes deja vu is that we cannot recall a memory that initially familiarized us with something we are now seeing, i.e. having seen a photo of an art object and not remembering seeing the photo but getting a sense of deja vu when you see it in a museum. 
If you have very frequent sensations of deja vu you may be having seizures of the temporal lobe, not uncommon after head trauma for example.  See your doctor if this is a persistent problem.

Question 10

is it possible for someone who has lost their personal identity and past memories, to get overwhelming deja vu experiences?

Accepted Answer

Yes, it's possible: Depending on the cause of the memory loss, these could be dissociative flashbacks.  That means the memories are still there somewhere but a defense mechanism called dissociation is keeping them from waking memory.  If the problem is not physical, a psychologist who specializes in this would be helpful in assisting you in answering this and maybe regaining some of your identity.
