Following the nighttime revelation, Samuel's behavior shifts dramatically. Earlier in the night, he had jumped out of bed with eagerness to answer Eli's calls, but his reaction to God's message is entirely different [אברבנאל]. Shaken by the harsh news, he remains in his bed until morning [ביאור שטיינזלץ]. Even after rising, he actively avoids approaching Eli. Instead, he turns to his regular daily duties, opening the doors to the House of God to prepare the Tabernacle for the day's service and allow visitors to enter.
Samuel avoids his mentor because he is deeply afraid to share the difficult prophetic vision he just experienced [מצודת ציון]. Eli is the man who raised and cared for him, and Samuel holds him in the highest respect and admiration [ביאור שטיינזלץ]. Delivering such terrible news to his caretaker is a frightening task.
This hesitation raises a significant question, as a prophet who hides a divine message commits a grave offense. However, in this specific instance, God did not actually command Samuel to deliver a message to Eli. God merely revealed His plans to the young man as a prophetic vision [מלבי״ם]. Because he was not formally sent on a mission to warn Eli, Samuel's silence is simply a natural human reaction born of fear and respect, rather than a forbidden concealment of prophecy.
