Venous return...: Bending or squatting "kinks" the inferior vena cava, it being a lower pressure system than the aorta, thereby decreasing venous return to the heart. If low blood volume due to dehydration, anemia etc., this decrease can be enough to prevent outward blood flow and cause syncope or near-syncope. Impaired response time to this change can also occur w/ increased vagal tone, like in vaso-vagal syncope.

Dizzy: This is known as orthostasis and is very common. Typically due to lack of appropriate fluid intake, it could also be a clue to a blood pressure issue. A quick check by your doctor would give us the answer. In the meantime, mind your hydration.
