My closest friend's only surviving child passed away 6 weeks ago due to a stupid reaquaintance with cocaine. Recently my friend has seen a tiny colored light many nights when she wakes suddenly from a deep sleep. The first night it was red, another night it was blue, most nights it is green. The light is about the size of a dime. My friend feels it is her son. If so, what might the color changes indicate?
FYI, this friend lost a 2yr old daughter to leukemia 30 years ago. After that child passed away, the mom saw on many occasions a cluster of pinpoints of light she felt was her daughter. Any comments on that apparition too would be of help.

Be kinder than you need to be. Everyone is dealing with something.
