The last few days
As all these changes continue, there comes a time when people feel very weak and are not able to get out of bed at all. From needing to sleep and rest a lot, people move into a phase where their sleep becomes deeper and they spend time drifting in and out of consciousness.
At times you may become confused, and not recognise your family or friends. You may also hear or see things which are not there (hallucinations). You may have thoughts or experiences which are like dreams, in which you are not sure whether things that you experience are real or not.
The drowsiness and confusion may be due to the chemical changes that are happening in the body and the build up of waste chemicals (toxins). They may sometimes be partly due to the medicines that you need to keep you comfortable. Sometimes, to the people around you, you may appear distressed and restless.
