Your guides can create situations and simulations for you. But that does not mean it will be 'nice' or cozy all the time.

To quote Kurt Leland:

Simulations are dreamlike environments in which we master skills pertaining to the astral body and plane. These environments are usually created and maintained by Facilitators–highly evolved souls who are working in nonphysical reality while between lifetimes on the physical plane. They’re usually more focused and intense than the average dream. They set a problem or task and often repeat themselves until the problem has been resolved or the task has been accomplished.

Ask your guides for learning experiences and to create them for you. Maybe this is the best way. You can trust them. As said, you might encounter difficulties and unpleasant things there. But it is like in the physical world too. Why would you expect everything to be a heavenly fairytale in the astral? Go for it and accept what they throw at you, just like you accept life's struggles in this world.
