A Touch from Satan
Scholars have said that if a person dreams of being touched by a passing thought (Ta'if) from Satan while engaged in remembrance of Allah, it may indicate that they have many enemies who wish to harm them but will not succeed. This is supported by the Quranic verse: "Indeed, those who fear Allah—when an impulse from Satan assaults them, they remember [Him]."
