During sleep I feel quite low and my dreams are quite disturbing. What does this mean?

• Personally I am not a dream expert, but what could possibly be happening is that consciously you've worked on something and now your subconscious is also working through it as you rest and sleep. I wouldn't worry too much about it, unless it's a frequent occurrence.
• If it is a frequent occurrence, I would look at the emotions I feel behind my dreams and proceed to flip this, using the memory flipping techniques in week 2.
• If you're having vivid dreams after memory flipping, this is a very common phenomenon.
