IF you are searching a bookshelf for a certain kind of book, that signifies that in life as well you are searching for knowledge and wisdom of some sorts and just don’t know what exactly you are looking for. So never stop that searching because you will eventually find it and be happy that you found exactly what you are looking for!
If you or the other person needs glasses to read it signifies that you will have little blinders on in your life and be fooled by close people in your life.
And that you won’t be able to see you problems clearly and that you will need some extra help in those matters.
In the dream if you or someone else is reading incoherently it is a bad omen of disappointment and hurt. And means that: you will be confused with some matters in life and not know what to do.
The advice is that you need to search for the knowledge that is needed to stop being confused. And figure out what you need in life to no longer be disappointed.
. If the book is a small book or a picture book the less knowledge you need, on the other hand if it is a big book that is a sign that you will receive quite a bit of knowledge.
