Do frequent dreams about illness and fear of it, despite adherence to religious duties, indicate a weakness in the strength of faith?

A believer must praise Allah for guidance and success in performing religious duties, and know that what befell him was not meant to miss him, and what missed him was not meant to befall him, and that he should fear none but Allah, as Allah the Almighty says: "Say: 'Nothing will befall us except what Allah has decreed for us; He is our Protector.' And upon Allah let the believers rely." And "So fear them not, but fear Me, if you are truly believers." Fear of something tangible and natural is not sinful. However, illusory fear of the intangible is not befitting for a Muslim. Consulting psychiatrists for help is permissible.
