The leaflet was extremely helpful.

I could especially relate to this part:
Thought disorder/muddled thinking
You find it hard to concentrate as your thoughts seem fuzzy or muddled. Your thinking feels bizarre and disconnected. You may be unable to finish a book that you have been reading or follow a TV programme.

The muddled thinking may affect your speech, so you may jump from one topic to another and after a while, you may not be able to remember what you were trying to say in the first place. This makes it difficult for people to follow your conversation.

You may believe that your thoughts are being interfered with:

someone or something is able to insert thoughts in your mind (you may feel like a particular thought it not yours);
someone or something is taking certain thoughts out of your mind - that your thoughts are disappearing.
Sometimes you may feel that other people can hear your thoughts or have access to them in some way.

I definitely believed people could hear my thoughts and I had the ability of mind control because my thoughts could strongly influence people's actions. Then I became paranoid that my thoughts were leaking and eventually it lead to believe that entities called Hummies lived inside the walls and were trying to steal my music and the whole thing became really complex so I won't go into details. I also had delusions that came out of the blue, that I was the goddess of music and that the entities came from musicians brains that were looking for inspiration from the music goddess (who was me). So I had a lot of paranoid thoughts and actions revolving around these beliefs.

Also, I had recently been manic before these delusions and paranoid thoughts entered my head. By the time I was fully delusional one morning, I didn't have any manic symptoms other than restlessness which is probably more due to the fact that I'm ADHD and not currently on my medication for it.

I'm going to show this leaflet to my therapist...so thank you! Now I'm going to look at the other link you provided.
