Is there any instrument that can record the pictures in the dream?

Dreams are like a mirror, reflecting everything during the day. When you wake up in the morning, you can record your dreams. You can use a pen and paper or a mobile phone. Mobile phones can use the voice bar function of the file transfer assistant in WeChat to describe dreams, or use Iflytek voice to text (Iflytek is the most powerful voice to text tool at present); When you are free during the day, you can put the words in your impression notes or other tools and date them. Students who know astrology can also post the horoscope at that time. Let's analyze the influence and reflection of planets on dreams.
