The phone... I have heard people say that they pick up the phone and hear departed loved ones, but I don't get that feeling here, I wonder if it is more to wake you up and make you walk about so you make contact?
I often hear the phone then when I get up to answer it I see and feel a presence, and realise they have woken me the only way they know how lol.
Candles are a lovely aid in this kind of situation, they are easy for energy to play with and move the flame
Ugh @ the smells lol, but they are confirmation, unless you have dodgey drains lol, but seems you have cleaned them so much can't be that

and I have no doubt when you have got though this current contact they will lesson and then only appear when needed
