For those you have lost a loved one and still miss them, you should know that their spirit will always be with you and your family. Talk to friends and relatives about any signs or dreams from them. You will be amazed by the stories others will tell about them.
Talk to your loved one like you normally would and they will hear you. And if you quiet your mind enough you should be able to hear them too. Before you go to bed at night, when you lay your head down on your pillow, let go of all your thoughts. Find a meditation technique that works for you.
