When i stand up suddenly i get a headache. is that normal?

sometimes if i am laying down and i get up fast my vision goes kind of weird and i get a 10 sec. headache. Is that similar to a grey-out in any way?

i do lay around and do nothing now, so it could be Orthostatic hypotension. i checked it on wikipedia. it isn't that bad. i just wanted to know what it was

you are experiencing a head rush, my dear. totally normal

Orthostatic hypotension (also known as postural hypotension and, colloquially, as head rush) is a sudden fall in blood pressure that occurs when a person assumes a standing position. Symptoms, which generally occur after sudden standing, include dizziness, lightheadedness, blurred vision, and syncope (temporary loss of consciousness).
