But I was standing and everything was a hue of blue all of the sudden and my hearing was being blocked. When I hurriedly layed down on the bed my body regained it normal composure after awhile.

I fell over today when I stood up and stretched off a couch. The next thing I knew my mom was telling me if I'm okay and to get up off the floor. She said that when I fell (I don't remember falling) that I started having spasms and throwing my arms and legs everywhere (I had a seizure.) I am scared now because I feel like I am going to have sleep paralysis.

If your vision fades, to avoid passing out, crouch down, put hands above your head, move your head up while pushing down on it with your hands. This causes your body to quickly rush blood back to your brain. Meaning you will instantly feel normal again.
Masked One (2 months ago)
Just came from the fainting video. We both get head rush very easily we don't need to stand up we can be lying down or sitting and stretch boom head rush it sometimes ain't nice.
Virgo Heart (2 months ago)
I want to know some more details. Like what might make this more likely to occur? Do certain foods help or make it worse? Does temperature effect the likelihood of it happening? I've noticed on hot Summer days I seem much more sensitive to it happening. Just like in cold winter days I seem more sensitive to charlie horses in my feet (Muscle tightening uncomfortably).

Lol i was laying down on the floor and once i got up to go to my kitchen i got light headed
Phoenix Franks (3 months ago)
The dizziness vertigo option “great joko space” (Google it) saved my life from further problems. I was light headed along with vertigo and would have debilitating instances. I was scared to drive my automobile since I had one particular spell while driving. I have been making use of this twice a day for 4 months and until now no more light-headedess, queasiness or dizziness.
Tanner Crane (3 months ago)
Yea i get all the time when i get up
Yarrow Justice (3 months ago)
This dizziness vertigo remedy “great joko space” (Google it) took away my mind spinning and helped with my dizziness. Annually I get vertigo for several days, but I`m no longer worried since I have this particular treatment solution now. It`s also non-drowsy so I did not get sleepy or feel fatigued during the day. I like this procedure!

Mandy Dubois (3 months ago)
Usually happens when I’m taking a bath or when I’m eating a hot soup or sitting in a hot kitchen will make me feel light headed but 2 weeks ago it got so bad my vision became cloudy and I Clouldnt really hear.

I acquired this dizziness vertigo solution “great joko space” (Google it) for my partner hadwho has different levels of dizziness for four to five. He started getting outcomes after four days, and now after a week, even though not 100% yet he`s had long periods of full relief. I am hoping this treatment will be the answer as well as he`ll have no more dizziness troubles to suffer from.

I fainted once when I was like 11. I am an athlete and I had surgery on both my feet and so I can't do any training with the casts.. Now I lay down for like 1 minute and my blood pressure goes down to the point where I feel like falling over.

Darragh Holden (5 months ago)
I received this dizziness vertigo remedy “great joko space” (Google it) for my partner hadwho has varying degrees of dizziness for four to five. He began having results after four days, and now after a week, despite the fact that not 100% yet he`s had long periods of full alleviation. Ideally, with extended use, he will be dizzy free before long.

Sydney Tonkin (5 months ago)
Yeahhhhhhh, except for me, my vision blurs completely to gray and I go entirely blind, and then my face turns numb and all of my muscles weaken and I’m incapacitated for about 30 seconds. And that happens at least 5 times a week. Sometimes multiple times in one day. That’s fun.
