Yes, you’re right. I am thinking that maybe as we near the time when we will see our beloveds in the clouds when Jesus returns and takes up all those who belong to Him and who are alive on this earth - that maybe those dear departed souls are just so eager for this soon to occur reunion - that sometimes they are breaking through from heaven - to let their loved ones know they are going to see them soon! Yours is going to see you soon! Hallelujah! (That is just an insight into a possible happening - not for sure).
One of the things I read that made a lot of sense was when you are grieving if the departed revealed themselves to us — for example in our dreams — would we even get out of bed... probably not and that would retard the purpose we have to live out here on earth, the departed have completed their set journey and we have to complete our own journey before we join them on the other side. This is why most mediums say don’t even try making contact until you are well into dealing with your loss... but I do know, for a fact, my husband was very much present in the beginning, the dogs let me know when he was here.
