My age is 44 and weight 65kgs. No addictions. Anemic with Hemoglobin level 10.5. Cholesterol level-normal.
Whenever I lie down or bend my head, I feel a bit dizzy and I feel normal again in about 10 seconds. Is this because of low Hemoglobin level or something with the brain?
I am a bit busy and I rarely get time to meet a doctor. So please help me out.

Is your blood pressure within normal range? That is where I would start if you were in my ER.

Yes. It is in normal limit. It was 110/80 when I checked it last time around a week ago.
Sorry for not adding it.
