When it happens to me, I have the Deja Vu (usually happens when I'm relaxed, in bed, almost asleep), The Deja Vu is usually of a dream that I have had, as if I'm slipping into a dream but then come out of it. It gets hard to breath, probably because of panic since it's a strange Deja Vu feeling, my body goes numb, and sometimes tingly, I get lightheaded and nauseous, I also usually zone out. It only lasts for about 1 to 2 minutes, and afterwards I can never remember what my Deja Vu was.
This sounds exactly like some sort of seizure, more likely Temporal Lobe Epilepsy... I was tested for epilepsy and the results came back showing nothing at all! I also used to have anxiety but because I'm literally never doing anything but laying down when it happens, I find it unlikely to be a panic attack, (I've had panic attacks before, I used to have really bad anxiety, the two are very different). And I'm not stressed much at all, apart from normal things like school but even then I don't see how me falling asleep can trigger this uncomfortable feeling if that was the cause...
Even though I don't get it often I just want to know what causes it and what it is. I've had it for about a year now and have experienced it about 20 to 30 times.
What makes it even more weird is the fact that I have experienced Deja Vu many times throughout my life and have only recently had these other side effects. Even while I've had these weird ones, occasionally I'll have a normal "I feel like I've done this or seen this before" with no physical reaction.
If all the symptoms for epilepsy are there, but it's not that, then I have no idea if I'll ever know... I hate it so much.
I just googled (for about the 50th time) the symptoms because as I was just falling asleep ten minutes ago, I got it.
I've never personally met anyone else with these symptoms and always feel so crazy when explaining to to someone, especially because they never understand; even my doctors don't understand.
In my case I get a feeling of dislocation, the smell of what I would describe as burning plastic, nausea and "aura" where I get images that I am certain (at the time) are from my dreams, the past or are from the future. Normally this is is accompanied by a feeling of dread or foreboding.
I believe it to be the TLE form of epilepsy. The symptoms match, epilepsy runs strong in my family (my brother, a 1st cousin and a 2nd cousin) and I have had 1 Grand Mal and 1 Petit Mal seizure in my life (brought on by other things and for the most part without the symptoms which we are discussing). While these episodes can occur at any time they are more likely to occur when I am fatigued, have long term stress or both. The symptoms are much weaker than they were when I was young.
If someone has this at the same level I do then my advice is don't worry about it too much, from the other posts many doctors leap to the wrong (and easiest) conclusions and this type of epilepsy at this level seems to be undetectable unless you are lucky and have one while being scanned. If you do not lose control and its only for a few seconds then why get yourself put on a bunch of drugs if they can analyze it at all?
If you are of a religious bent I find that a few prayers help me. If you aren't so lucky (hah!) then try to do something quick that reassures you......for all I know since it is a brain thing activating that part of our mind may ease the episode in the temporal lobe and end it.
My daughter started having deja vu episodes at the age of six, mixed with other symptoms like dizziness, auras-hearing muffled voices, tunnel vision, fear, feeling like she was remembering a dream etc. She was diagnosed with everything from low blood sugar to asthma, migraines, silent migraines, anxiety attacks and finally focal seizures. But at 16 they decided the episodes had changed and could not be epilepsy after all and discharged her from the practice, a pediatric epilepsy and migraine center. Before she was discharged a neuro-psychologist did extensive testing and determined that the episodes were NOT panic attacks but a newly discovered and little understood neurological condition, with no name, where the brain short circuits, "like a computer with too many tabs open that crashes", in the doctors exact words. The brain becomes over stimulated and crashes, leaving the person in a cognitive brain fog with what can be a slow recovery to full function. Like I said, her treating doctor discharged us soon after because it did not fit his practice standards. I think the real issue is doctors that do not want an unsolvable case on their records. Now at 17 she is being really crippled by these episodes. Sudden deja vu, overwhelming since of fear that comes on very suddenly. Feeling dizzy and like she will pass out. Auras of sounds, smelling things that are not there, visual (double vision), a chemical taste, Nausea or cramps, hiccups, racing heart. The fear ends suddenly at about 60 seconds or a little longer. When I say suddenly ends I mean instantly gone. She will be saying "I am so afraid, so afraid" snap "Oh, the fear is completely gone now". I have had panic attacks and I have never had the fear just end suddenly. The rest of the symptoms do not go away quickly though. Afterwards she is totally exhausted. Weak feeling. Sometimes she can't speak well or find the words needed for communication. She becomes aphasic at times. When we ask her about it later she describes it as information suddenly not being able to enter her brain, like a traffic jam. Music, TV, reading, someone speaking to her, they all jam up and make no sense to her. She can't remember many details of what happened during the episodes. The brain fog can last from hours to days or weeks. She loves to study and research, but these episodes shut her down. I have gone rounds with her former neurologist trying to get a referral or help. I have called the neuro psychologist and asked repeatedly for a referral also. They simply do not know what to do with it or where to send her.
