What has happened to me - I was preparing to go to bed and all of a sudden everything went dark. I found my way to bed by memory and lay down. I saw shadows and got scared and just closed my eyes and surprizing I went to sleep. when i woke up things were back to normal. went to dr. he ordered mri of head and caroted artery and heart - all normal. what happened?
How long did this last? Was it dark or light in the room? This is pure conjecture but it could have been a momentary drop in bp. If I get up too fast from a sitting or stooped position everything will go black on me and it takes a good moment for it all to come back. Sometimes when I am in the shower I will see stars after I bend down to get the soap or something. Considering you had a clean mris it is likely you are OK but I would keep an eye on it. I would also consider going and getting your eyes evaluated as well. But all in all sometimes weird stuff happens and we never know what it was.
I agree with Michelle -- an eye evaluation is in order. Sometimes retinal problems can cause symptoms like these -- better safe than sorry. Also seems to me migraines can have similar symptoms. Good luck to you.
