Narrative:

I believe the main cause of the problem was I lost control of the aircraft when I was following vector heading direction. I was completely in the cloud for 10 to 15 minutes. I got disoriented and the plane was descending and I was able to recover from the unusual altitude when I see the lights from the city at about 3;000 feet. Luckily; norcal approach was able to amend me with VFR. I requested to head to embassy suite VFR check point to avoid from busy sjc airspace. Controller was kind enough to accommodate my request. Finally; I landed airplane safely.
