For the past 3 days i've tried to wild. the problem is i cant relax i have all this thoughts in my head. the closest i got was starting to see images and colors (or it was just me being insane i'm not sure if colors and pictures are a sign of getting close). Another thing that caught my attention is my pulse becomes rapid and i have a hard time getting enough air. i assume i'm just excited to have a lucid dream but i really need to relax and i don't know how.

does anyone have any great ways to clear your mind?
any tips on how to relax as well?
