Yes, actually we can;

"Arthur Aron, a social psychologist at Stony Brook University in New York, has done brain scans on people newly in love and found that after that first magical meeting or perfect first date, a complex system in the brain is activated that is essentially "the same thing that happens when a person takes cocaine.""
Explain to me how something would be useful if there was no way to prove, either it's existence or it's validity.
I actually don't agree that a brain scan is "measuring" happiness...it allows us to get a visual of a part of the brain that is activated, but it's hardly quantifiable in a practical sense. How can it be measurable when we don't even have a unit for measurement for it?
What about intuition then? My intuition has saved my ass on a number of occasions (out in the wilderness by myself) but if you tell most people "I had a feeling so I--for no logical reason--moved positions and a few minutes later the place I was previously standing was struck by lightening" (true story btw). I can't tell you what intuition looks like, how much I feel, what it smells or tastes like...just that I felt something. I think this is what Drive is talking a/b w/certain forms of deja vu....a feeling you can't really explain...it just "is."
i would call it instinct even humans have instinct
What kinda instinct would that be? I do agree its instinct but that would mean some unknown sense is telling us to move away from danger... I dont know if this is off topic but I had a prophetic dream once, I dreamed my friend came over to chill and he asked me if I had any smokes, then the same friend knocked on my window waking me up from that dream and asked if I had any smokes.
As for Deja vu I experience 3 kinds
1. dream
2. realizing something will happen before it happens
3. feeling like an occorance happened before
Are these all deja vu or is only the third true deja vu?
Is there any science behind "deja vu" ?

What sets deja vu apart is the feeling. There are many times we ask ourselves, have I seen this movie before, have I had this conversation with this person already, did I dream about this. Even though we feel confused during those times, we do not feel strange or uncanny. When we 'realize' something will happen just before it does, we get a similar surrealistic feeling, but it is a different circumstance brought on by a different mechanism.
There are several theories, but no solid study. This is because deja vu occurs without warning, lasts briefly and leaves no evidence to be studied. AFAIK, it has never been consistently recreated in a laboratory setting. It's likely that many factors, both internal and external, can trigger deja vu, but the most strange feeling times are probably when our brain connects the present to a memory, but in no clear way. The past memory may only be a fragment of a skeleton because it's old or was not deemed important enough to hold details in the first place. In some cases we may even strangely connect the present to memories from just minutes or seconds ago. It is also possible that a chemical or something in the brain causes a feeling of remembrance that is connected to no memory at all, but because we are used to that feeling being connected to a memory, we assume it is.
It has been observed that deja vu seems to be more frequent in mental patients, and also commonly proceeds temporal lobe epilepsy attacks, so it does seem that deja vu represents a disturbance in normal brain function.

Or it could simply be a glitch in the Matrix...
