Although you don't have to lie down, you may sit in a chair or lie on your bed, the main thing is to be in a safe place so you can be vulnerable. Set your affection on Jesus.
You might like to soak while listening to intimate worship music with meaningful words that quiet your soul and help you draw near to God. As you reflect on the cross and all that Jesus has lovingly purchased for you, begin confessing your sins to Him and longing to be close to Him. After a few moments, you will become aware of the Holy Spirit's unseen presence.
People experience Him in many ways: a weight upon your body, an electric tingling upon your hands or face, or a warm sensation of love going through your heart which connects you to Him. This is how you grow to love anyone, by a series of several encounters that bond you together. It is not only a rational process; your heart must be engaged.
Experiencing God's presence is what will cause you to love the Lord with all your heart and soul. (Matthew 22:37) Humble yourself before Him. Give all your worries and cares to the Lord talking to Him about them.
Pray a prayer like this. "Lord Jesus, I invite You to come and search my heart. Come close and let me know your love." Let worship rise up inside you and give yourself to the Lord. If you become distracted, then re-focus on Jesus. Remind yourself why you are soaking and listen to the worship music.
