Here are some examples of the kinds of thoughts that clutter people’s minds

Sad memories

Memories of unfortunate events fill people with hate, disappointment and regret. People find it hard to forgive themselves for the mistakes that they have done in the past.

Happy memories 

Instead of using happy memories for inspiration, many people only find longing. There is constant longing for moments that were long gone. People try to relive those memories by forcing their current situations to work in exactly the same manner as it did when they were happy in those memories. 

Expectations

Expectations are ‘false memories’ of the future. People do not know what will happen yet, but they play out various scenarios in their mind that cause them to expect certain things to happen. They expect people to behave exactly as they did in their false memories.

Apprehensions

Also false memories, apprehensions are expectations of negative events to happen. These thoughts cause people to be extremely wary. They resist the natural flow of events for fear that their negative false memory will actually play out. They set limitations and restrictions for themselves, thinking it would be safer for them to be boxed inside their psychological defenses.
