I am a recent convert to Islam. Sometimes I face difficulty while focusing during salat. Random images come in my mind. Yesterday while praying salat ul layl in middle of my salat with my eyes open I saw an image of my face half burned. And it dropped my blood pressure as if I saw it in real.

Some recommendations:

1- Before you pray, recite Suras 113 and 114.

2- Spray vinegar in room that you’ll be praying in.

3- Make sure your body/clothes are fully pure.

4- If you can, bring a pair of pigeons to your room.

5- Dedicate each prayer to a gift God has given you and while praying think of that gift.

Insha’Allah this helps.
