Intuition/psychic connection always works to one very important universal law, which is we cannot "see" or "know" with out permission. This is because we will interfere with someone else's free will, and free will is one of our greatest gifts -- the right to be able to choose. So you will get mixed results if the person in the photo you have hasn't given you permission to know information about them as this isn't in their free will. You can read someone's personality from a photo, but not information about their life.
When reading a photo in this way, we look into the person's eyes with curiosity about who they are. We then may get feelings that we didn't just have or see clairvoyant pictures in our own mind. Sometimes these pictures are from our own lives. Clairvoyance uses our imaginations like a film scene whenever it has to convey information, even scenes from your own history.
A person can sense when someone is tuning into them, even when they are miles away. The feeling is often unpleasant, just as being watched by someone in the street can give you the same feeling. Some people don't feel it as they are less sensitive, in the same way that a person might not be ticklish.
Having a photo of someone under your pillow is a good way to set an intention that you would like to connect with someone in your sleep. But it isn't important as it is the intention that is the important thing. However, both parties must share the same intention. Sleep stroking is still an energetic annoyance!
It is possible to make a telepathic connection through psychometry, but again not without permission. With telepathy, you don't hear words in your head from the other person's thoughts, it is a deep form of empathy, connection and inner knowing, which can be beautiful when found in relationships.
