Orthostasis.: Sounds like your blood pressure temporarily drops when you rise. This is called orthostasis and has a variety of causes but is generally due to low circulating blood volume or inadequate response of your autonomic nervous system to changes in posture. If you are adequately hydrated and have enough salt on board and your symptoms persist you may need to see your doc to consider further testing.

Low blood pressure: You may have orthostatic hypotension(low blood pressure with positioning). Please make sure to drink and eat well. Dehydration and anemia may lead to low blood pressure. Pls consult your doc.
