T – A complicated dream. But it is not just two dimensions, but I suppose it can be divided into outer and inner – see
https://dreamhawk.com/dream-encyclopedia/dimensions-of-human-experience/ You dream appears to put you in a learning situation that you are working on – the workplace and school classroom. The message is that you would do better if you leave what you have been doing and be involved in artwork and yoga – that is not suggesting doing those things but a change to that area of interest – an artist and yoga teachers.
You have taken many people’s influence into you - When you think about a lover, a friend or a person you know, you are only taking in your thoughts, impressions and feelings about them. So many people do not realise that they have an inner person equally as powerful as the external person you know. You have taken in millions of bits of memory, lessons learnt, life experiences along with all the feelings or problems met by meeting or living with them, and they change you and make you the person you are. The memories and experience we gather unconsciously change us and are not lost. It is part of you and is symbolised in dreams as a person or event. Such an inner person can appear in dreams because you still carry the memories or impressions of them, and so they influenced what you hold within you.
So the artist, the yoga teachers, your sister and A, are all in you and you appear to be going through a learning experience because of your life experience with these people. So you need to ‘digest’ those experiences and influences.
Digestion is a very important function not just for our body but also for our mind and spirit. I have seen people become very ill in mind because they have not digested their experience or what they have learnt at school or the lessons and experience of a relationship long gone. And digestion is a Life function. Life in us is often greatly overlooked and our dreams are one way of showing us how we have not surrendered our life experience to that function. See
