If you feel like someone is watching you when you pray, maybe it’s because they are.
God watches over us all, and is intimately involved and present in our prayers to Him. God literally wanted a relationship with you so badly, He sent His son, Jesus Christ, to die for us, so you could spend eternity with Him in heaven. God also loves you eternally and unconditionally.
So why on Earth would God not want to make His presence known when you talking with Him.
Biblical Perspective:
Many scriptures emphasize God's nearness. For example, Psalm 145:18 states, The LORD is near to all who call on him, to all who call on him in truth. Acts 17:27 also highlights God intention for people to seek Him and find Him.
