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 is this deja vu feeling i'm having? when i get it i feel weak and hot, clammy, and my heart starts to beat fast until i sit or lay down.

Accepted Answer

Not sure but: Sounds like your nervous system is activated by something and these are symptoms of that. Have you ever heard of a pheochromocytoma before? Catecholamines? You should go see a good physician who will examine you and do an appropriate work-up.

Question 3

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 5

is it normal to have deja vu?

Accepted Answer

Deja vu: For brief periods of time & in response to stressor, yes.

Question 6

what is the definition or description of: deja vu?

Accepted Answer

"Already Seen": Déjà vu is a feeling that a current event or experience has been experienced previously. It is thought to be an aberration of memory in which the "time stamp" of an event becomes mis-assigned to make it seem as if the event occurred previously.  Almost everyone has experienced rare déjà vu events. When frequent it is rarely associated with temporal lobe epilepsy.

Question 7

why do some people have deja vu ? and what does it really mean?

Accepted Answer

That depends on: Who you ask and how often it happens.  In combination with other symptoms, it can indicate a type of seizure disorder (partial complex).

Question 8

why do i have these feelings of deja vu when meeting someone new?

Accepted Answer

Double perception: When you're meeting someone new, you focus on them.  But your subconscious is still perceiving the rest of the world.  During your introduction at some point, your focus becomes less defined, and you begin to consciously perceive the rest of the world the way you normally would, but since there are memories of those perceptions recently laid down in your subconscious mind, they seem familiar.

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.
