Hello Je,
Thank you for sharing your dream. Please take everything back to the Holy Spirit for confirmation as He Alone gives the final/correct interpretation. I will provide my thoughts from a Christian perspective as I’m not sure what your background is.
The therapist could represent the Holy Spirit (also called the Counsellor and Comforter). The 5 year plan could represent that you’ve been given grace (5=grace) and it is time to cleanse and wipe your hands of any impurity/sin. It reminds me of the caution in James 4:7-9. The entire chapter of James 4 might bless you. The encouraging thing is that the “therapist” is with you and willing to work with you and is affirming you so be blessed!
Shalom!
